Abu Hurairah (RA) reported that 'Umar happened to pass by Hassan as he was reciting verses in the mosque. He (Hadrat 'Umar) looked towards him (meaningfully), whereupon he (gassin) said: I used to recite (verses) when one better than you (the Holy Prophet) had been present (here). He then looked towards Abu Hurairah (RA) and said to him: I adjure you by Allah (to tell) if you had not heard Allah's Messenger ( صلی اللہ علیہ وسلم ) as saying: (Hassan), give a reply on my behalf; Allah I help him with Ruh-ul-Qudus. He (Abu Hurairah (RA)) said: By Allah, it is so (i. e. the Holy Prophet ( صلی اللہ علیہ وسلم ) actually said these words).

Ibn Musayyib reported that Hassan said to a circle in which there was also Abu Hurairah (RA): Abu Hurairah (RA) , I adjure you by Allah (to tell) whether you-had not heard Allah's Messenger ( صلی اللہ علیہ وسلم ) saying like this.

'Abdul Rahman reported that he heard Hassin bin Thabit al-Ansari call Abu Hurairah (RA) to bear witness by saying: I adjure you by Allah if you had not heard Allah's Apostle ( صلی اللہ علیہ وسلم ) saying: Hassin, give a reply on behalf of the Messenger of Allah. O Allah, help him with Ruh-ul-Qudus. Abu Hurairah (RA) said: Yes, it is so.
