Merits of the Helpers in Madinah (Ansaar)
Chapter: The emigration of the Prophet (saws) to Al-Madina
Narrated Al-Bara:
Abu Bakr bought a (camel's) saddle from `Azib, and I carried it for him. `Azib (i.e. my father) asked Abu Bakr regarding the journey of the migration of Allah's Messenger (ﷺ). Abu Bakr said, "Close observers were appointed by our enemies to watch us. So we went out at night and travelled throughout the night and the following day till it was noon, then we perceived a rock and went towards it, and there was some shade under it. I spread a cloak I had with me for Allah's Messenger (ﷺ) and then the Prophet (ﷺ) layed on it. I went out to guard him and all of a sudden I saw a shepherd coming with his sheep looking for the same, the shade of the rock as we did, I asked him, 'O boy, to whom do you belong?' He replied, 'I belong to so-and-so.' I asked him, 'Is there some milk in your sheep?' He replied in the affirmative. I asked him, 'Will you milk?' He replied in the affirmative. Then he got hold of one of his sheep. I said to him, 'Remove the dust from its udder.' Then he milked a little milk. I had a water-skin with me which was tied with a piece of cloth. I had prepared the water-skin for Allah's Messenger (ﷺ) . So I poured some water over the milk (container) till its bottom became cold. Then I brought the milk to the Prophet and said, 'Drink, O Allah's Messenger (ﷺ).' Allah's Messenger (ﷺ) drank till I became pleased. Then we departed and the pursuers were following us."
