Al-Lu'lu Wal-Marjan 1280 — The Book of Al-Adâhi (Sacrifices) (Animals slaughtered on the day of 'Eid Al-Adha)

Jundub Narrated from:

On the day of Nahr the Prophet صلى الله عليه وسلم offered Salât (prayer) and delivered the Khutba (religious talk) and then slaughtered the sacrifice and said, "Anybody who slaughtered (his sacrifice) before he offered Salât should slaughter another animal in lieu of it, and the one who has not yet slaughtered should slaughter the sacrifice mentioning Allâh's Name on it." ( Sahîh Al-Bukhâri, Hadîth No. 101, Vol. 2)
