On the authority of Abu Hurayrah (ra):
I heard the Messenger of Allah (ﷺ) 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 the excessive questioning and their disagreeing with their Prophets that destroyed [the nations] who were before you."[Bukhari & Muslim] (FR)
