Sayyiduna Ali (may Allah be pleased with him) narrates in the square of Kufah: When the Messenger of Allah (peace and blessings be upon him) conquered Makkah, some people of Quraysh came to him and said: Some of our slaves and servants have joined you; their purpose is not the religion but only to flee from our livestock and our fields. The Messenger of Allah (peace and blessings be upon him) said: "O people of Quraysh! By Allah, you will surely establish the prayer and pay the zakah, or else I will send against you a man who will strike your necks for the sake of the religion." Then he said: "It will be me, or the one who is mending the sandal." Sayyiduna Ali says: At that time I was mending the sandal of the Messenger of Allah (peace and blessings be upon him). Then Sayyiduna Ali (may Allah be pleased with him) said: I heard the Prophet (peace and blessings be upon him) say: "Whoever lies about me will enter the Fire." This hadith is sahih (authentic) on the condition of Muslim, but the two Shaykhs (Bukhari and Muslim) did not record it.
