It is narrated from Sayyiduna Bara’ bin Azib (may Allah be pleased with him) that when the Prophet (peace and blessings be upon him) was migrating from Makkah Mukarramah to Madinah Munawwarah, he felt thirsty on the way. Coincidentally, a shepherd of goats passed by. Sayyiduna Abu Bakr Siddiq (may Allah be pleased with him) says: I took a bowl and milked a little milk in it for the Prophet (peace and blessings be upon him), and brought it to him. The Prophet (peace and blessings be upon him) drank it until I was pleased.
