Ibn Musayyib (may Allah have mercy on him) says: Sayyiduna Hassan (may Allah be pleased with him) said in a gathering, in which Sayyiduna Abu Hurairah (may Allah be pleased with him) was also present, "O Abu Hurairah! I ask you by Allah, did you hear the Messenger of Allah (peace and blessings be upon him) say: 'Hassan! Respond on my behalf, Allah Almighty will support you with the Holy Spirit.'?" He said: "Yes."
