The Messenger of Allah ﷺ said, "Now then, people, I am only a human being, and the messenger of my Lord is about to come to me and I shall answer the call. I am leaving among you two weighty things. The first is the Book of Allah, which contains guidance and light, so take hold of the Book of Allah and cling to it." The hadith continues.
قال رسول الله ﷺ: أما بعد! ألا أيها الناس، فإنما أنا بشر يوشك أن يأتي رسول ربي فأجيب، وأنا تارك فيكم ثقلين: أولهما كتاب الله فيه الهدى والنور، فخذوا بكتاب الله واستمسكوا به الحديث.
Muslim narrated it in Fadail al-Sahabah (2408:36) through several routes from Ismail bin Ibrahim bin Ulayyah, who said, Abu Hayan told me, Yazid bin Hayan told me, from Zayd bin Arqam, who said, and then he related the hadith at length concerning the merits of the Prophet's ﷺ household.He also narrated it through the route of Jareer, from Abu Hayan with this same chain, and added in it, "The Book of Allah, in it is guidance and light. Whoever holds fast to it and takes hold of it is upon guidance, and whoever misses it goes astray."
