Reports on Hassan bin Thabit (may Allah be pleased with him)

Sayyiduna al-Bara' bin Azib (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said to Sayyiduna Hassan bin Thabit (may Allah be pleased with him): "Satirise the polytheists! Indeed, Allah Almighty will support you through the Holy Spirit (Ruh al-Qudus)."
Imam al-Tabarani recorded it in al-Mu'jam al-Saghir. Its chain contains Ayyub bin Suwayd al-Ramli, who is da'if (weak); Ibn Hibban declared him thiqah (trustworthy) and said: He had a poor memory.

Sa'id bin Jubayr narrates: A man came to Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) and said: Hassan the accursed has come. Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) said: He is not accursed; he waged jihad alongside the Prophet (peace and blessings be upon him) with his tongue and with his life.
Imam Abu Ya'la recorded it. Its chain contains Khadij bin Mu'awiyah bin Hudayj, who is da'if (weak), though he has also been declared trustworthy.
