What did you do on this day in the company of Allah's Messenger (ﷺ)? Thereupon he said: One of us pronounced Tahlil, and he met with no disapproval, and one of us pronounced Takbir, and he also met with no disapproval.
Sahih Muslim Book 15, Hadith 302
← Previous Hadith We were along with Allah's Messenger (way peace he upon him) in the morning of 'Arafa (9th of Dhu'l-Hijja). Some of us pronounced Takbir and some of us Tahlil La ilaha ill-Allah). And to those of us who pronounced Takbir, I said: By Allah, how strange it is that you did not care to ask him: What did you see Allah's Messenger (ﷺ) doing (on this occasion)?

Sahih Muslim Book 15, Hadith 301 Next Hadith → I said to Anas b. Malik in the morning of 'Arafa: What do you say as to pronouncing Talbiya on this day? He said: I travelled with Allah's Apostle (may peace he upon him) and his Companions in this journey. Some of us pronounced Takbir and some of us pronounced Tahlil, and none of us found fault with his companion.
