It is narrated from Hazrat Abu Bakrah (may Allah be pleased with him) that once I saw the Prophet (peace and blessings be upon him) on the pulpit and Hazrat Imam Hasan was with him. Sometimes he would turn towards the people and sometimes he would look at Imam Hasan and say, "This son of mine is a leader, and Allah Almighty will bring reconciliation between two groups of Muslims through him."
