Aisha's narration continues: "At that time the Prophet was in Mecca, and he said to the Muslims: 'In a dream I have been shown your migration place, a land of date palm trees, between two mountains, the two stony tracts.' So, some people migrated to Medina, and most of those people who had previously migrated to the land of Ethiopia, returned to Medina. Abu Bakr also prepared to leave for Medina, but Allah's Messenger said to him: 'Wait for a while, because I hope that I will be allowed to migrate also.' Abu Bakr said: 'Do you indeed expect this? Let my father be sacrificed for you!' The Prophet said: 'Yes.' So Abu Bakr did not migrate for the sake of Allah's Messenger in order to accompany him. He fed two she-camels he possessed with the leaves of As-Samur tree that fell on being struck by a stick for four months.
"One day, while we were sitting in Abu Bakr's house at noon, someone said to Abu Bakr: 'This is Allah's Messenger with his head covered coming at a time at which he never used to visit us before.' Abu Bakr said: 'May my parents be sacrificed for him. By Allah he has not come at this hour except for a great necessity.'
So Allah's Messenger came and asked permission to enter, and he was allowed to enter. When he entered, he said to Abu Bakr: 'Tell everyone who is present with you to go away.' Abu Bakr replied: 'There are none but your family. May my father be sacrificed for you, 0 Allah's Messenger!' The Prophet said: 'I have been given permission to migrate.' Abu Bakr said: 'Shall I accompany you? May my father be sacrificed for you, 0 Allah's Messenger!' Allah's Messenger said: 'Yes.' Abu Bakr said, '0 Allah's Messenger! May my father be sacrificed for you, take one of these two she-camels of mine.' Allah's Messenger replied: '(I will accept it) with payment.'
So we prepared the baggage quickly and put some journey food in a leather bag for them. Asma, Abu Bakr's daughter, cut a piece from her waist belt and tied the mouth of the leather bag with it, and for that reason she was named "Dhat-un-Nitaqain" (i.e. the owner of two belts).
'Then Allah's Messenger and Abu Bakr reached a cave on the mountain of Thaur and stayed there for three nights. Abdullah Ibn Abi Bakr who was an intelligent and sagacious youth, used to stay (with them) overnight. He used to leave them before day break so that in the morning he would be with Quraish as if he had spent the night in Mecca. He would keep in mind any plot made against them and when it became dark he would (go and) inform them of it.
Amir Ibn Fuhaira, the freed slave of Abu Bakr, used to bring the milk sheep (of his master, Abu Bakr) to them a little while after nightfall in order to rest the sheep there. So they always had fresh milk at night, the milk of their sheep, and the milk which they warmed by throwing heated stones in it. Amir Ibn Fuhaira would then call the herd away when it was still dark (before daybreak). He did the same in each of those three nights.
Allah's Messenger and Abu Bakr had hired a man from the tribe of Bani Ad-Dail from the family of Bani Abd Ibn Adi as an expert guide, and he was in alliance with the family of Al-As Ibn Wa'il As-Sahmi and he was in the religion of the infidels of Quraish. The Prophet and Abu Bakr trusted him and gave him their two she-camels and took his promise to bring their two she camels to the cave of the mountain of Thaur in the morning after three nights later. And (when they set out), 'Amir Ibn Fuhaira and the guide went along with them and the guide led them, along the seashore."
