ʿUmar came to the Mosque while Hassan was reciting a poem. (ʿUmar disapproved of that). On that Hassan said, "I used to recite poetry in this very Mosque in the presence of one (i.e. the Prophet ﷺ ) who was better than you." Then he turned towards Abu Huraira and said (to him), "I ask you by Allah, did you hear Messenger of Allah ﷺ saying (to me), "Retort on my behalf. O Allah! Support him (i.e. Hassan) with the Holy Spirit?" Abu Huraira said, "Yes."
