Sahih Muslim Book 4, Hadith Number 1022.

Chapter : The excellence of the prayer and the way it is begun and the excellence of Ruku’ and moderation in it and prostration and moderation in it, etc.

This Hadith has been reported by Ma’mar on the authority of al-Zuhri with the same chain of transmitters, but here no mention has been made of Mina or ‘Arafa, and he said: It was in the Farewell Pilgrimage or on the Day of Victory.
