Usama b. Zaid (Allah be pleased with him) reported
I was sitting behind Allah's Messenger (ﷺ) on the riding animal from 'Arafat. As Allah's Messenger (ﷺ) reached the left side of the mountain which was situated near Muzdalifa , he made the camel kneel down and made water and then came back. I poured water and he , performed light ablution. I then said : Messenger of Allah , it is time for prayer. Thereupon Allah's Messenger (ﷺ) said : The prayer awaits you (at the next station , Muzdalifa). Allah's Messenger (may peaced be upon him) rode on until he came to Muzdalifa and observed prayer. Then al-Fadl (Allah be pleased with him) sat behind Allah's Messenger (ﷺ) and reached (Muzdalifa) in the morning.
