Narrated Aisha:

Rarely did the Prophet (ﷺ) fail to visit Abu Bakr's house everyday, either in the morning or in the evening. When the permission for migration to Medina was granted, all of a sudden the Prophet (ﷺ) came to us at noon and Abu Bakr was informed, who said, "Certainly the Prophet (ﷺ) has come for some urgent matter." The Prophet (ﷺ) said to Abu Bark, when the latter entered "Let nobody stay in your home." Abu Bakr said, "O Allah's Messenger (ﷺ) ! There are only my two daughters (namely `Aisha and Asma') present." The Prophet (ﷺ) said, "I feel (am informed) that I have been granted the permission for migration." Abu Bakr said, "I will accompany you, O Allah's Messenger (ﷺ) !" The Prophet (ﷺ) said, "You will accompany me." Abu Bakr then said "O Allah's Messenger (ﷺ) ! I have two she-camels I have prepared specially for migration, so I offer you one of them. The Prophet (ﷺ) said, "I have accepted it on the condition that I will pay its price."

حَدَّثَنَا فَرْوَةُ بْنُ أَبِي الْمَغْرَاءِ، أَخْبَرَنَا عَلِيُّ بْنُ مُسْهِرٍ، عَنْ هِشَامٍ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ لَقَلَّ يَوْمٌ كَانَ يَأْتِي عَلَى النَّبِيِّ صلى الله عليه وسلم إِلاَّ يَأْتِي فِيهِ بَيْتَ أَبِي بَكْرٍ أَحَدَ طَرَفَىِ النَّهَارِ، فَلَمَّا أُذِنَ لَهُ فِي الْخُرُوجِ إِلَى الْمَدِينَةِ لَمْ يَرُعْنَا إِلاَّ وَقَدْ أَتَانَا ظُهْرًا، فَخُبِّرَ بِهِ أَبُو بَكْرٍ فَقَالَ مَا جَاءَنَا النَّبِيُّ صلى الله عليه وسلم فِي هَذِهِ السَّاعَةِ، إِلاَّ لأَمْرٍ حَدَثَ، فَلَمَّا دَخَلَ عَلَيْهِ قَالَ لأَبِي بَكْرٍ ‏"‏ أَخْرِجْ مَنْ عِنْدَكَ ‏"‏‏.‏ قَالَ يَا رَسُولَ اللَّهِ إِنَّمَا هُمَا ابْنَتَاىَ‏.‏ يَعْنِي عَائِشَةَ وَأَسْمَاءَ‏.‏ قَالَ ‏"‏ أَشَعَرْتَ أَنَّهُ قَدْ أُذِنَ لِي فِي الْخُرُوجِ ‏"‏‏.‏ قَالَ الصُّحْبَةَ يَا رَسُولَ اللَّهِ‏.‏ قَالَ ‏"‏ الصُّحْبَةَ ‏"‏‏.‏ قَالَ يَا رَسُولَ اللَّهِ إِنَّ عِنْدِي نَاقَتَيْنِ أَعْدَدْتُهُمَا لِلْخُرُوجِ، فَخُذْ إِحْدَاهُمَا‏.‏ قَالَ ‏"‏ قَدْ أَخَذْتُهَا بِالثَّمَنِ ‏"‏‏.‏

Abu Bakr (may Allah be pleased with him) was the closest friend to the Prophet ﷺ, and his companion in the migration. He (may Allah be pleased with him) was endowed with the greatest share of faith and belief compared to all Muslims, so much that had his faith been weighed against that of all people, his faith would have outweighed theirs. This hadeeth underlines an aspect of the strength and genuineness of the relationship between the Prophet ﷺ and Aboo Bakr (may Allah be pleased with him). The Mother of the Believers ‘Aa’ishah (may Allah be pleased with her) stated that the Prophet ﷺ frequently visited his friend Aboo Bakr (may Allah be pleased with him) in the early days of Islam in Makkah. He ﷺ used to visit him either at sunrise or sunset. When Allah, Exalted is He, granted the Prophet ﷺ the permission to migrate from Makkah to Al-Madeenah, the Prophet ﷺ visited Aboo Bakr’s house at noon, and he ﷺ would not have visited him at such an unusual time except for an urgent and serious matter! Given the seriousness and gravity of the situation, jeopardizing the lives of the Prophet ﷺ and Aboo Bakr (may Allah be pleased with him), the Prophet ﷺ asked to speak with him in private to inform him of the migration. Aboo Bakr (may Allah be pleased with him) informed the Prophet ﷺ that only histwo daughters, namely ‘Aa’ishah and Asmaa’ (may Allah be pleased with them), were in the house. Thereupon, the Prophet ﷺ informed him that he ﷺ was granted the permission to migrate to Al-Madeenah. Since Aboo Bakr (may Allah be pleased with him) eagerly waited for that greatopportunity, he (may Allah be pleased with him) asked the Prophet ﷺ to accompany him during the journey, despite his knowledge of the gravity of the situation. The Prophet ﷺ granted him the permission to accompany him. In fact, he ﷺ had commanded him to remain in Makkah and did not grant him the permission to migrate to Al-Madeenah earlier with the other Companions (may Allah be pleased with them), so to accompany him when he would be granted the permission (from Allah, Exalted is He). Aboo Bakr (may Allah be pleased with him) had bought and prepared two she-camels for the Prophet ﷺ and himself for that journey. When permission was granted to the Prophet ﷺ to migrate to Al-Madeenah, he (may Allah be pleased with him) offered one of the two she-camels to the Prophet ﷺ, who accepted it on the condition that he ﷺ pay him its price. The hadeeth highlights the virtues and merits of Aboo Bakr (may Allah be pleased with him). It is also deuced therefrom that the Prophet ﷺ keenly sought the benefit of Aboo Bakr (may Allah be pleased with him) as he ﷺ refused to accept the she-camel without paying its price..
