that he heard Hassan bin Thabit Al-Ansari asking the witness of Abu Huraira, saying, "O Abu- Huraira! I beseech you by Allah (to tell me). Did you hear Allah's Messenger (ﷺ) saying' 'O Hassan ! Reply on behalf of Allah's Messenger (ﷺ). O Allah ! Support him (Hassan) with the Holy Spirit (Gabriel).'?" Abu Huraira said, "Yes."

← Previous Hadith that he heard Abu Huraira in his narration, mentioning that the Prophet (ﷺ) said, "A Muslim brother of yours who does not say dirty words." and by that he meant Ibn Rawaha, "said (in verse): 'We have Allah's Messenger (ﷺ) with us who recites the Holy Qur'an in the early morning time. He gave us guidance and light while we were blind and astray, so our hearts are sure that whatever he says, will certainly happen. He does not touch his bed at night, being busy in worshipping Allah while the pagans are sound asleep in their beds.' "
