It is narrated from Hazrat Abu Saeed Khudri (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: I am leaving among you two important things, one of which is connected to 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 be separated from each other until they come to me at the Pond of Kawthar.
