Sahih Muslim Book 6, Hadith 16
This hadith has been transmitted by Shu'ba with the same chain of narrators and it is narrated from Simt, and the name of Shurahbil has not been mentioned, and he said that he had gone to a place called Dumin, situated at a distance of eighteen miles from Hims.
I went along with Shurahbil b. al-Simt to a village which was situated at a distance of seventeen or eighteen miles, and he said only two rak'ahs of prayer. I said to him (about it) and he said: I saw 'Umar observing two rak'ahs at Dhu'l-Hulaifa and I (too) said to him (about it) and he said: I am doing the same as I saw the Messenger of Allah (ﷺ) doing.
We went out from Medina to Mecca with the Messenger of Allah (ﷺ) and he prayed two rak'ahs at each time of prayer till we returned to Medina. I said: For how long did he stay in Mecca? He said: (For) ten (days).
