Abu Bakr Siddiq reported:
As we went along with Allah's Messenger ( صلی اللہ علیہ وسلم ) from Mecca to Medina, we passed by a shepherd and Allah's Messenger ( صلی اللہ علیہ وسلم ) was feeling thirsty. He (Abu Bakr Siddiq) said: I milked for him a small quantity of milk (from his goat) and brought it to him (the Holy Prophet), and he drank it and I was very happy.
