It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Be content with what I have left with you. Indeed, those who were before you were destroyed because of their many questions and their disagreeing with their prophets. Whatever I command you, do as much of it as you are able, and whatever I forbid you, refrain from it."
