Muhammad ibnYezid Albani, who said:
I was present at Ja'far ibn Muhammad's (as), when Umar ibn Qays al-Masir and Abu Hanifa and Umar ibn Dharr, together with a group of their companions, called upon him. Then they asked him about faith (al-Iman). He said: The Prophet, peace be upon him and his progeny, said: "An adulterer (and a fornicator) does not commit that sin at the same time being a Mu’min, and a thief does not steal at the same time being a Mu’min, and one does not drink liquor (intoxicant) while being a Mu’min."
We started looking at each other, then Umar ibn Dharr said: "What shall we call them?"
He, peace be upon him, said: "Call them the way Allah has called them because of their deeds. Allah in Qur'an says: 'And for a male thief and a female thief, cut off their hands' (al-Maedah V:38) and 'As for the fornicatress and the fornicator, flog each of them a hundred stripes.' (al-Noor V:2)." Hearing this, they stared at each other.
Muhammad ibn Yazid says: Bishr ibn Umar ibn Dharr, who was with them, reported to me that: When we left, Umar ibn Dharr said to Abu Hanifa: "Why did you not ask him who had reported from the Prophet?" He (Abu Hanifa) said: "What can I say to a man who (authoritatively) says: The Prophet, peace be upon him and his progeny, said."
