باب مَا يَسْتُرُ مِنَ الْعَوْرَةِ

Narrated Abu Huraira:

On the Day of Nahr (10th of Dhul-Hijja, in the year prior to the last Hajj of the Prophet (ﷺ) when Abu Bakr was the leader of the pilgrims in that Hajj) Abu Bakr sent me along with other announcers to Mina to make a public announcement: "No pagan is allowed to perform Hajj after this year and no naked person is allowed to perform the Tawaf around the Ka`ba. Then Allah's Messenger (ﷺ) sent `Ali to read out the Surat Bara'a (at-Tauba) to the people; so he made the announcement along with us on the day of Nahr in Mina: "No pagan is allowed to perform Hajj after this year and no naked person is allowed to perform the Tawaf around the Ka`ba."

حَدَّثَنَا إِسْحَاقُ، قَالَ حَدَّثَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ، قَالَ حَدَّثَنَا ابْنُ أَخِي ابْنِ شِهَابٍ، عَنْ عَمِّهِ، قَالَ أَخْبَرَنِي حُمَيْدُ بْنُ عَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ، أَنَّ أَبَا هُرَيْرَةَ، قَالَ بَعَثَنِي أَبُو بَكْرٍ فِي تِلْكَ الْحَجَّةِ فِي مُؤَذِّنِينَ يَوْمَ النَّحْرِ نُؤَذِّنُ بِمِنًى أَنْ لاَ يَحُجَّ بَعْدَ الْعَامِ مُشْرِكٌ، وَلاَ يَطُوفَ بِالْبَيْتِ عُرْيَانٌ‏.‏ قَالَ حُمَيْدُ بْنُ عَبْدِ الرَّحْمَنِ ثُمَّ أَرْدَفَ رَسُولُ اللَّهِ صلى الله عليه وسلم عَلِيًّا، فَأَمَرَهُ أَنْ يُؤَذِّنَ بِبَرَاءَةَ قَالَ أَبُو هُرَيْرَةَ فَأَذَّنَ مَعَنَا عَلِيٌّ فِي أَهْلِ مِنًى يَوْمَ النَّحْرِ لاَ يَحُجُّ بَعْدَ الْعَامِ مُشْرِكٌ، وَلاَ يَطُوفُ بِالْبَيْتِ عُرْيَانٌ‏.‏
