Volume 8, Book 78, Number 658:
Narrated ‘Abdullah bin ‘Amr bin Al-As:
While the Prophet was delivering a sermon on the Day of Nahr (i.e., 10th Dhul-Hijja-Day of
slaughtering the sacrifice), a man got up saying, “I thought, O Allah’s Apostle, such-and-such a thing
was to be done before such-and-such a thing.” Another man got up, saying, “O Allah’s Apostle! As
regards these three (acts of Hajj), thought so-and-so.” The Prophet said, “Do, and there is no harm,”
concerning all those matters on that day. And so, on that day, whatever question he was asked, he
said, “Do it, do it, and there is no harm therein.”
