صحيح مسلم

Al-Bara' reported: When Allah's Messenger (ﷺ) went forth from Mecca to Medina, Suraqa b. Malik b. Ju'shum pursued him. Allah's Messenger (ﷺ) invoked curse upon him, and his horse sank (in the desert). He (Suraqa) said: (Allah's Messenger), invoke blessings for me and I will do no harm to you. He (the Holy Prophet) then supplicated Allah. (At that time) he (the Holy Prophet) felt thirsty, and they happened to pass by a shepherd. Abu Bakr Siddiq said: I took hold of a bowl and milked some milk into it for Allah's Messenger (ﷺ) and gave it to him. He drank it and I was pleased.
