binding; the choice to follow another person’s opinion arises only when the Prophet’s command is unknown and that person is knowledgeable about him and his Sunnah. Under these conditions, following another person’s opinion is permissible, not obligatory. No one is obliged to follow anyone’s opinion other than his. At most, doing so is permissible; declining to adopt that opinion would not constitute disobedience to Allah and His Messenger.
How can this compare with the one whom everyone accountable under religious law must follow, whom they are forbidden to oppose, and for whose word they must abandon every other opinion? No one’s judgment or word has authority alongside his, just as no one may legislate alongside him. As for anyone else, following his words is obligatory only when he commands what the Prophet commanded and forbids what he forbade, acting solely as a transmitter and conveying what already exists, rather than originating teachings and laying foundations.
Whoever formulates opinions and establishes principles according to his own understanding and interpretation does not thereby oblige the Muslim community to follow them or refer disputes to them. They must first be examined against what the Prophet brought (1). If they accord and agree with it, and it attests to their soundness, they are then accepted. If they contradict it, they must be rejected and discarded. If neither is clear, judgment on them is suspended. At best, it is permissible either to use them in adjudication and issuing fatwas or to refrain from doing so. But that (2) doing so should be obligatory and mandatory—no, certainly not (3)!
