so he (‘Umar’) feared that he would refer to the Messenger of Allah (May peace be upon him); therefore he allowed him.
Sunan Abi Dawud Book 43, Hadith 242
← Previous Hadith Umar passed by Hassan when he was reciting verses in the mosque. He looked at him. Thereupon he said: I used to recite verses when there was present in it the one who was better than you (i.e. the Prophet).

Sunan Abi Dawud Book 43, Hadith 241 Next Hadith → The Messenger of Allah (ﷺ) used to setup a pulpit in the mosque for Hassan who would stand on it and satirise those who spoke against the Messenger of Allah (ﷺ). The Messenger of Allah (ﷺ) would say: The spirit of holiness (i.e. Gabriel) is with Hassan so long as he speaks in defence of the Messenger of Allah (ﷺ).
