Abu Huraira 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 Huraira and said to him: I adjure you by Allah (to tell) if you had not heard Allah's Messenger (ﷺ) as saying: (Hassan), give a reply on my behalf; Allah I help him with Ruh-ul-Qudus. He (Abu Huraira) said: By Allah, it is so (i. e. the Prophet actually said these words)

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

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