A) All praise is for Allah alone and may the Peace and Blesssings be on His messenger, and his family, and his companions.

To proceed:

It is upon a Muslim to follow what came from Allah and His Messenger(s) if he is able to take the rulings by himself, and if he is not able [to do] that, he is to ask the people of knowledge in what is difficult for him from the matters of his deen, and ask the most knowledgeable who he can reach from the people of knowledge and ask them orally or by writing.

And it is not permissable for a Muslim to follow the madhhab of the Immamate Shi'ah, the Zaidi Shi'ah, nor what resembles them from the people of innovation (ahl-ul-bid'ah) like the Khawaarij, Mu'tazilah, Jahmiah, or others. And about attributing themselves to some of the four known mathaahib, then there is no harm in that if he is not fanatic to the madhhab that he is attributing himself to and he does not go against the evidences for its sake.

And from Allah is tawfeeq, and may the Peace and Blessings of Allah be on His messenger, his family, and his companions.

Question No. 1 from Fatwa No. 9783

Q) Is it permissable to combine the four known mathaahib and to practice on it, instead of choosing the madhhab followed in a certain region?

A) All praise is for Allah alone and may the Peace and Blesssings be on His messenger, and his family, and his companions.

To proceed:

The obligation on a Muslim is to follow the two revelations, the Book and the Sunnah, and what is inclusive from what is based on them, and that is if the person is from the people of knowledge. And if he is not, then he is to follow who is most trustworthy of those he knows from the people of knowledge.

And from Allah is tawfeeq, and may the Peace and Blessings of Allah be on His messenger, his family, and his companions.
