Narrated Zaid bin Arqam, may Allah be pleased with both of them:
that the Messenger of Allah (ﷺ) said: Indeed, I am leaving among you, that which if you hold fast to them, you shall not be misguided after me. One of them is greater than the other: The Book of Allah is a rope extended from the sky to the earth, and my family - the people of my house - and they shall not split until they meet at the Hawd, so look at how you deal with them after me.
