Hadith 1622
Narrated Abu Huraira: In the year prior to the last Hajj of the Prophet when Allah's Apostle 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 Ka`ba.' (See Hadith No. 365 Vol. 1)
