Should one subject be learnt from one shaykh or more than one?
be to Allaah.
I advise the seeker
of knowledge not to learn from every shaykh in one subject (i.e., to
learn each subject from one shaykh), such as learning fiqh from more
than one shaykh, because the scholars differ in the way they derive
evidence from the Qur’aan and Sunnah, and they also differ in their
opinions. So you should choose one scholar from whom to learn fiqh or
(Arabic) grammar and so on, i.e., learn one subject from one shaykh.
If the shaykh has knowledge of more than one subject, then stay with
him, because if you learn fiqh, for example, from this one and that
one, then there is a difference of opinion between them, what will your
position be as a student? You will be confused and in doubt. But if
you stick to one scholar for a particular subject, this will give you
peace of mind.
