Narrated `Aisha
Hassan bin Thabit asked the permission of Allah's Messenger (ﷺ) to lampoon the pagans (in verse). Allah's Apostle said, "What about my fore-fathers (ancestry)?' Hassan said (to the Prophet) "I will take you out of them as a hair is taken out of dough." Narrated Hisham bin `Urwa that his father said, "I called Hassan with bad names in front of `Aisha." She said, "Don't call him with bad names because he used to defend Allah's Messenger (ﷺ) (against the pagans).
Narrated Al-Haitham bin Abu Sinan
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.' "
Narrated Abu Salama bin `Abdur-Rahman bin `Auf
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."
Narrated Al-Bara
