Sahih Bukhari Volume 6, Book 65, Hadith 4657

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

Narrated By 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."
