Volume 4, Book 53, Number 402:
Narrated Abu Huraira:
Abu Bakr, on the day of Nahr (i.e. slaughtering of animals for sacrifice), sent me in the company of
others to make this announcement: “After this year, no pagan will be allowed to perform the Hajj,
and none will be allowed to perform the Tawaf of the Ka’ba undressed.” And the day of Al-Hajj-ul-
Akbar is the day of Nahr, and it called Al-Akbar because the people call the ‘Umra Al-Hajj-ul-
Asghar (i.e. the minor Hajj). Abu Bakr threw back the pagans’ covenant that year, and therefore, no
pagan performed the Hajj in the year of Hajj-ul-Wada’ of the Prophets.
