On the authority of Abu Hurayrah (may Allah be pleased with him) who said: I heard the Messenger of Allah (peace be upon him) say:

What I have forbidden for you, avoid. What I have ordered you [to do], do as much of it as you can. For verily, it was only their excessive questioning and disagreeing with their Prophets that destroyed [the nations] who were before you.

[Al-Bukhari & Muslim]
