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 Messenger (ﷺ) 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."

حَدَّثَنَا سَعِيدُ بْنُ عُفَيْرٍ، قَالَ حَدَّثَنِي اللَّيْثُ، قَالَ حَدَّثَنِي عُقَيْلٌ، عَنِ ابْنِ شِهَابٍ، وَأَخْبَرَنِي حُمَيْدُ بْنُ عَبْدِ الرَّحْمَنِ، أَنَّ أَبَا هُرَيْرَةَ ـ رضى الله عنه ـ قَالَ بَعَثَنِي أَبُو بَكْرٍ فِي تِلْكَ الْحَجَّةِ فِي مُؤَذِّنِينَ، بَعَثَهُمْ يَوْمَ النَّحْرِ يُؤَذِّنُونَ بِمِنًى أَنْ لاَ يَحُجَّ بَعْدَ الْعَامِ مُشْرِكٌ، وَلاَ يَطُوفَ بِالْبَيْتِ عُرْيَانٌ‏.‏ قَالَ حُمَيْدُ بْنُ عَبْدِ الرَّحْمَنِ ثُمَّ أَرْدَفَ رَسُولُ اللَّهِ صلى الله عليه وسلم بِعَلِيِّ بْنِ أَبِي طَالِبٍ، وَأَمَرَهُ أَنْ يُؤَذِّنَ بِبَرَاءَةَ‏.‏ قَالَ أَبُو هُرَيْرَةَ فَأَذَّنَ مَعَنَا عَلِيٌّ يَوْمَ النَّحْرِ فِي أَهْلِ مِنًى بِبَرَاءَةَ، وَأَنْ لاَ يَحُجَّ بَعْدَ الْعَامِ مُشْرِكٌ، وَلاَ يَطُوفَ بِالْبَيْتِ عُرْيَانٌ‏.‏
