Sayyidah Aisha (RA) narrated: The Prophet (SAW) had placed a pulpit for Hassan in the mosque. He would stand on it and present proud poetry eulogising Allah’s Messenger (SAW) or, she said: He would respond to the charges against Allah’s Messenger (SAW). And, Allah’s Messenger (SAW) would say, “Allah helps Hassan through Jibril when he boasts or responds.”
[Ahmed 2491, Abu Dawud 501]
