It is narrated from Sayyiduna Abdul Rahman bin Awf (may Allah be pleased with him) that when the Messenger of Allah (peace and blessings be upon him) conquered Makkah, he went towards Ta'if and besieged it for nineteen or eighteen days but did not conquer it. Then he went some distance further in the morning or the evening, then made camp, then at midday he said: "O people! I am your forerunner, and I enjoin you to treat my family ('itrah, the People of the House) well, and your meeting place with me is the Pool (al-Kawthar). By the One in whose Hand is my soul! They must establish the prayer and pay the zakah, or else I will send to them a man from myself (or he said: like myself) who will strike the necks of their fighters and take their offspring captive." The people thought that it would be Abu Bakr or Umar, but he (peace and blessings be upon him) took Sayyiduna Ali (may Allah be pleased with him) by the hand and said: "This is he."
