What was the instruction given to `Ali bin Abi Talib (saw) by the Prophet Muhammad (peace be upon him) when he sent him to recite Surat Bara'a at Mina on the Day of Nahr?
 Narrated Humaid bin `Abdur-Rahman:                     Abu Huraira said, "During that Hajj (in which Abu Bakr was the chief of the pilgrims) Abu Bakr sent me along with announcers on the Day of Nahr ( 10th of Dhul-Hijja) in Mina to announce: "No pagans shall perform, Hajj after this year, and none shall perform the Tawaf around the Ka`ba in a naked state." Humaid bin `Abdur Rahman added: Then Allah's Apostle sent `Ali bin Abi Talib (after Abu Bakr) and ordered him to recite aloud in public Surat Bara'a. Abu Huraira added, "So `Ali, along with us, recited Bara'a (loudly) before the people at Mina on the Day of Nahr and announced; "No pagan shall perform Hajj after this year and none shall perform the Tawaf around the Ka`ba in a naked state."
