Sulaym ibn Qays says: “Hasan ibn Mu’atamat and myself were in Makkah when Abu Dhar stood up and held the chain of the door (of Ka’abah) and then very loudly said on the occasion of Hajj.
“O people those who know, know me, and those who do not know me, I am Jundub ibn Janadah. I am Abu Dhar. O people, I have heard your Prophet saying: “The example of my Ahlulbayt in my Ummah is like Noah’s ark in his community. Whoever boarded it was saved and whoever left it drowned, and it is like the door of Hitta and Bani Israeel.”
O people, I have heard your Prophet saying: “I am leaving two things with you. Until you stay attached to them you will not deviate – the Book of Allah and my Ahlulbayt.”
He mentioned the whole hadith.”
When he returned to Medina, Uthman called him and said: “What was the reason for saying what you said on the occasion of Hajj?” He replied: “It was a promise that the Holy Prophet (SAW) had taken from me, and had commanded me about it.”
Uthman asked: “Who is a witness over this for you?” Ali (AS) and Miqdad both stood up and bore witness. Then they went away, and while the three were going. Uthman said: “This man and his companions think they are something.”
