Muhammad ibn Ja‘far narrated to us, Shu‘bah narrated to us, from Sulayman, who said: I heard Zayd ibn Wahb narrating from Hudhayfah: The Messenger of Allah (peace and blessings of Allah be upon him) narrated two hadiths to us. I have already seen one of them, and I am awaiting the other. Then he mentioned the hadith.
