It also contains what appears to be obligatory according to the Book but its repeal is signified by the Prophet’s action (sunnah) or that which appears compulsory according to the Prophet’s action but the Book allows not following it. Or there are those which are obligatory in a given time but not so after that time. Its prohibitions also differ.

There are also those of which a small portion is also acceptable (to Allāh) but they are capable of being expanded. [2]
