Avoid what I have forbidden you from; and do as much as you can, of what I have ordered you. Indeed, those before you were ruined because of their excessive questioning and disagreeing with their prophets. [Al-Bukhari]

«ما نهيتكم عنه فاجتنبوه، وما أمرتكم به فأْتُوا منه ما استطعتم، فإنما أَهلَكَ الذين من قبلكم كثرةُ مسائلهم واختلافهم على أنبيائهم». [صحيح.] - [متفق عليه.]
