In the year prior to the last Hajj of the Prophet ﷺ when Messenger of Allah ﷺ made Abu Bakr the leader of the pilgrims, the latter (Abu Bakr) sent me in the company of a group of people to make a public announcement: 'No pagan is allowed to perform Hajj after this year, and no naked person is allowed to perform Tawaf of the Kaʿba.' (See Hadith No. 365 Vol. 1) (Using translation from Bukhārī 1622)
أَخْبَرَهُ أَنَّ أَبَا بَكْرٍ بَعَثَهُ فِي الْحِجَّةِ الَّتِي أَمَّرَهُ عَلَيْهَا رَسُولُ اللهِ ﷺ قَبْلَ حَجَّةِ الْوَدَاعِ فِي رَهْطٍ يُؤَذِّنُ فِي النَّاسِ «أَلَا لَا يَحُجَّنَّ بَعْدَ الْعَامِ مُشْرِكٌ وَلَا يَطُوفُ بِالْبَيْتِ عُرْيَانٌ»
