Sahih al-Bukhari 5807

'Urwa related that 'A'isha said, "Some people emigrated to Madina and Abu Bakr prepared to emigrate. The Prophet, may Allah bless him and grant him peace, said, 'Take your time. I hope to be given permission.' Abu Bakr said, 'My father be your ransom, do you hope for that?' He said, 'Yes.' Therefore Abu Bakr kept himself back in order to accompany the Prophet, may Allah bless him and grant him peace. He fed two riding-camels he had on acacia leaves which had been knocked off with a stick for four months." 'Urwa said that 'A'isha said, "While we were sitting in our house around midday, someone said to Abu Bakr, 'This is the Messenger of Allah, may Allah bless him and grant him peace, coming with his head covered at a time at which he did not used to come to us. Abu Bakr said, 'May my father and mother be his ransom, by Allah, he has only come at this hour because something has happened.' The Prophet, may Allah bless him and grant him peace, came and asked for permission to enter and was given permission and he entered. When he entered, the Prophet, may Allah bless him and grant him peace, said to Abu Bakr, 'Send out those who are with you.' He said, 'They are my family, Messenger of Allah, may my father be your ransom!'. He said, 'I have been given permission to leave.' He asked, 'In company, may my father and mother be your ransom, Messenger of Allah?' The Messenger of Allah, may Allah bless him and grant him peace, said, 'Yes.' Abu Bakr said, 'Take one of these two she-camels, Messenger of Allah, may my father be your ransom.' The Messenger of Allah, may Allah bless him and grant him peace, said, 'I will take it for a price.'" She said, "We prepared what they needed for the journey as quickly as possible and we put food for the journey in a bag. Asma' bint Abi Bakr cut a piece from her belt and used it to tie the mouth of the bag, and that is why she is called, 'She of the two belts.'" She said, "Then the Prophet, may Allah bless him and grant him peace, and Abu Bakr reached a cave in a mountain called Thawr and remained in it for three nights. 'Abdullah ibn Abi Bakr, who was a young boy who was clever and quick-witted, would spend the night with them and he would leave them before dawn and would be in Makka with Quraysh in the morning as if he had spent the night there. He did not hear of anything which they were planning about them but that he would remember it and bring them the news of that when it became dark. 'Amir ibn Fuhayra, the freed slave of Abu Bakr, would graze some milk sheep and bring them to them a hour after nightfall. They would spend the night in ease until 'Amir ibn Fuhayra called out when it was dark. He did that each of the three nights."
