In the context of  Taqleed a "lay person" is defined as one who knows little
regarding the  Arabic language, and about Islam in general - even though they may  be
intelligent in other fields of knowledge. Proficiency to read Arabic  titles concerning the
Qur'an and Sunnah but devoid of any formal Islamic  studies with a qualified instructor
would also place a person within the  ambit of laity. In addition, students who have taken
formal courses in  Islamic sciences but have failed to develop acumen would also fall
within  this classification. The above mentioned are under an obligation to  practice
Taqleed. They must follow a specific Imam and Mujtahid because they  simply do not
have the ability to refer to the Qur'an and Sunnah directly nor  can they differentiate
between what is apparently contradictory and give  scholarly preference to one opinion
over the other. Shaykh Khatib of Baghdad  wrote:
"As for those who should apply Taqleed it is the lay person who does  not know
the methods of extracting Islamic rules. It is permissible for such  a person to follow one
specific Imam and act upon his Fatwas. This is so  because he does not possess the tools
for Ijtihad so his duty is to follow,  just as a blind person must follow someone who is able
to see for determining  the direction of the Qiblah." 
The Muqallid (follower) on this level  cannot get caught up in discussions of
proofs to see which Imam's view is  stronger. His duty is merely to appoint one Mujtahid
and follow his opinions  in all matters. This is because he is not academically capable of
making  judgments of that kind. So much so that even if this person finds a Hadith  which
apparently contradicts the opinion of his appointed Imam, he should not  resort to
following the Hadith, but rather adhere to his Imam's opinion. He  should assume that he
has not understood the meaning or context of the Hadith  appropriately or he should have
no doubt that his Imam has a stronger proof  than the Hadith in question, which he may
not be aware of.
This might  seem to be a ludicrous proposition, explaining away the Hadith and act
upon  the opinion of his Imam. The truth is that at this level of Taqleed no  other
alternative exists. Freedom to practice upon any Hadith one sees,  completely regardless of
the fact that Ahadith literature is spread over  several hundred thousand Ahadith contained
in over more than three hundred  compilations, would lead to a distortion of the Shari'ah
and result in chaos  and confusion, because understanding how to extract rules from the
Qur'an and  Sunnah is so vast an enterprise that even if one spent a lifetime endeavoring  to
achieve this, it would not be possible to claim expertise. Many times, an  apparent
meaning is understood from a certain Hadith but after careful  examination of the
principles of the Qur'an and Sunnah, and other equally  authentic Ahadith a totally
different meaning emerges. Acting upon the  apparent meaning of a Hadith will give
rise to as many differing  interpretations of a Hadith as there are intellects. I myself have
witnessed  many people who have studied the Qur'an and Sunnah and (without the aid of  a
scholar or a school) have made outrageous conclusions which are far removed  from the
truth. A friend very keen to study books on Hadith believed  adamantly that although he
was a follower of Imam Abu Hanifa, he would not  hesitate to leave his school of thought
if he found any Hadith, which  contradicted it. Based on this belief, he informed someone,
in my presence,  that a person's wudu or ablution is not broken unless one actually hears
wind  passing or smells it. I understood immediately from where this misconception  arose.
It is true that such a Hadith exists in Tirmidhi. The full Hadith  narrated by Imam Tirmidhi
reads:
"Abu Hurairah RA narrated that the  Prophet sallalahu alaihi wa sallam said: "Wudu does
not break unless there is  a sound or smell."
Imam Tirmidhi then narrated another Hadith, which is very  similar to the one above:
"If anyone of you is sitting in the mosque and  feels air between his buttocks, he should not
leave unless he hears a sound  or smells something."
My friend assumed that wudu did not break, according  to this narration, unless
there was evidence of a sound or a smell. The truth  is quite far from it. All the scholars
unanimously agree that this Hadith  concerns only those people who are habitually
suspicious of their wudu  breaking 'without a valid reason. The Prophet sallalahu alaihi wa
sallam  informed that they would need more than their suspicions to confirm the  invalidity
of their wudu. This is elucidated in other narrations such as the  one in Abu Dawood:
"If anyone of you are in the mosque and feels some  movement in his buttocks and then
starts to doubt whether he has broken his  wudu or not, should not leave unless he smells
an odour or hears a  sound."
Abu Dawood himself has further narrated from Abdullah ibn Zubair  RA that the
Prophet sallalahu alaihi wa sallam explained this to person who  was continuously suspicious
of his wudu. Only a person who is qualified and  an expert in Hadith can reach this
conclusion. Acting upon reading one Hadith  from one book would only lead to
misconceptions and errors such as the one  committed by the person in question. What is
alarming is that he had been  acting upon the apparent meaning of the Hadith for a long
time. He did not  know how many prayers he had offered without wudu.
Likewise, if the  concession to leave an Imam's opinion for the sake of a Hadith is
granted,  the following Hadith narrated in Tirmidhi would appear to go against  the
collective (Jumhoor) Fatawa of the Imams.
"Ibn Abbas RA narrated that  the Prophet sallalahu alaihi wa sallam combined the
afternoon prayer (Zuhr)  with the late afternoon prayer (Asr) and the evening prayer
(Maghrib) with  the night prayer ('lsha) in Madinah even though there was no rain or  fear
present. Ibn Abbas RA was asked to explain this action and said that the  Prophet sallalahu
alaihi wa sallam did not wish any burden to fall on his  community."
The initial impressions one gains from this Hadith is the  permissibility to combine
Zuhr with Asr and Maghrib with Isha even without  being a traveler, in fear or excessive
rain. All the scholars, including the  people who claim to follow Hadith literally, see the
Hadith as meaning an  apparent combining of the prayers in question. The Prophet sallalahu
alaihi  wa sallam offered Zuhr when it was almost time for Asr and then Maghrib when  it
was almost time for 'Isha. This interpretation would be in line with all  other principles and
proofs from the Qur'an and Sunnah, whereas the first and  apparent meaning would not.
These are two examples from many, where a person  who is not qualified can very easily
mislead himself and others into  interpreting texts incorrectly. For this reason Scholars
have declared that a  non-scholar who is not capable of understanding Hadith should learn
from a  person who has expertise in the field. The Taqleed of an Imam or Mujtahid  is
made when there is an apparent contradiction in the Qur'an and Sunnah. If  there is a
difference of opinion between Imam Abu Hanifa and Imam Shaf'iee,  proofs exist for both
sides. In instances where there exist discordant proofs  for two sides, the person who
cannot judge which one of the two scholars,  argument is stronger should follow a specific
Imam and Mujtahid.
If one  adopts Imam Abu Hanifa to be as one's Imam and finds a Hadith  which
apparently supports Imam Shaf'iee opinion, he should not leave Imam Abu  Hanifa's
opinion because there must be a stronger reason (according to the  Hanafi view) for Imam
Abu Hanifa (or Mujtahids within the Hanafi school) to  leave the Hadith. None can
conclude that the Hanafi view is against the  Hadith. This is all the more apparent in a
scenario where the follower does  not have the academic qualifications to judge which
proof is stronger, even  if this follower finds a Hadith which contradicts his Imam, he
should not  forsake his Imam's opinion but rather assume that he has not understood  the
meaning of the Hadith in its appropriate context. The principle of this  approach is very
simple. A person who is in need of legal advice goes to a  reputable lawyer and attorney.
He does not resort to researching the  books of law independently. If he approaches a legal
expert whose reputation  is flawless and about whom he knows that he would not mislead
him - and finds  that there is an apparent contradiction in the law and what he is  advising,
he should still listen to the attorney and act upon his advice. He  should still give his
attorney the benefit of the doubt and assume that the  law may be interpreted in a way,
which is different to his own understanding.  This approach is necessary (and accepted) because everyone knows that  understanding the law requires tremendous expertise and
acumen. This  expertise is all the more necessary where the law is deduced from the
Qur'an  and the Sunnah and extrapolated to the full corpus of the Shari'ah, which  covers
the whole ambit of human existence. Scholars have indicated that the  lay person should
not resort to understanding the Quran and Sunnah directly,  but rather consult scholars and
jurists. This has been promoted to the extent  that if a lay person is given a Fatwa which
turns out to be wrong, the  liability will be with the one who gave the Fatwa and not on the
one who  sought and applied it, but if a lay person decides to consult the texts himself  and
assumes an incorrect interpretation and acts upon it, he will not be  freed from blame for
his mistake since it was not his responsibility to  search for an answer independently.
For example, cupping while fasting does  not invalidate a person's fast. If a lay
person asks a Mufti if cupping  breaks his fast and the Mufti, for whatever reason, replies
in the  affirmative, then the burden of the lay person eating and drinking for the  remainder
of the day will fall on the Mufti and not on the lay person. The  author of Al-Hidayah, a
renowned book on Hanafi law, said that the lay person  would have to make up the fast but
there will be no additional penalty on  him. The author of Hidayah explained this by
saying that the Fatwa is a legal  proof for the lay person, but if this same lay person read in
Abu Dawood and  Tirmidhi that the Prophet sallalahu alaihi wa sallam passed by a person
who  was cupping his blood while fasting and said:
"Both the one cupping the one  cupped have invalidated their fast." 98
He decided that his fast had broken  and started to eat and drink, then according to Imam
Abu Yusuf, he would have  to make up the fast and be responsible for the penalty of
fasting sixty days  consecutively. Abu Yusuf explained: "The lay person must follow the
scholar  and the jurist since he is not able to reach a correct conclusion by reading  the
Hadith."
To summarise, the first level of Taqleed is for the lay  person who should follow
the opinion of his Imam.
