Zaid b. Arqam reported God's messenger as saying, "I am leaving among you something of such a nature that if you lay hold of it you will not go astray after I am gone, one part of it being more important than the other: God's Book, a rope stretched from heaven to earth, and my close relatives who belong to my household. These two will not separate from one another till they come down to the Pond, so consider how you act regarding them after my departure." Tirmidhi transmitted it.
