Hazrat Abu Saeed Khudri (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: I am leaving among you two important things, one of which is greater than the other; one is the Book of Allah, which is a rope hanging from the sky to the earth, and the other is my Ahl al-Bayt. These two things will not separate from each other until they come to me at the Pond of Kawthar.
