The Qur'an enjoins the following of the Prophet (peace be upon him) and makes it clear to him. The details of many provisions are known only by them, such as the number of prayers and the amounts of zakaah. The Qur'an has been preserved with the knowledge of attribution, injury and modification, and whoever responds has to accept the Qur'an himself by way of transportation. "Whoever obeys the Messenger has obeyed Allah" [Women: 80]
