That sūrah IX of the Qur'ān contains a proclamation made to the people at the pilgrimage is stated in v. 3 of the sūrah itself. As to how much of the sūrah was contained in the proclamation, there is, however, no agreement either in Moslem tradition or among European scholars. The tradition that the proclamation was made by 'Alī at the pilgrimage of the year IX is very generally accepted. The story is given by Ibn Hishām (ed. Wuestenfeld, p. 921): “When the Barā'a (sūrah IX) was revealed to the messenger of Allah, it was suggested to him that he should send it to Abū Bakr, who had already been sent to lead the pilgrimage. But he said: ‘No one shall act instead of me but a man of my own household.’ Thereupon he summoned 'Alī b. Abī Ṭālib, and said to him, ‘Go with this message from the beginning of the (sūrah) Barā'a, and proclaim among the people on the day of sacrifice, when they are gathered in Minā, that no unbeliever will enter Paradise, and that after this year no polytheist shall perform the pilgrimage, and no naked person shall make the circuit of the House.’” The story then proceeds to relate that 'Alī set out on the prophet's camel, overtook Abū Bakr and made the proclamation at the time and in the terms which the prophet had appointed.
