Narrated 'Aisha:

(the wife of the Prophet) "I do not remember my parents believing in any religion other than the Religion (of Islam), and our being visited by Allah's Apostle in the morning and in the evening. One day, while we were sitting in the house of Abu Bakr (my father) at noon, someone said, 'This is Allah's Apostle coming at an hour at which he never used to visit us.' Abu Bakr said, 'There must be something very urgent that has brought him at this hour.' The Prophet ﷺ said, 'I have been allowed to go out (of Mecca) to migrate.' "

حَدَّثَنَا إِبْرَاهِيمُ، أَخْبَرَنَا هِشَامٌ، عَنْ مَعْمَرٍ،. وَقَالَ اللَّيْثُ حَدَّثَنِي عُقَيْلٌ، قَالَ ابْنُ شِهَابٍ فَأَخْبَرَنِي عُرْوَةُ بْنُ الزُّبَيْرِ، أَنَّ عَائِشَةَ، زَوْجَ النَّبِيِّ ﷺ قَالَتْ لَمْ أَعْقِلْ أَبَوَىَّ إِلاَّ وَهُمَا يَدِينَانِ الدِّينَ، وَلَمْ يَمُرَّ عَلَيْهِمَا يَوْمٌ إِلاَّ يَأْتِينَا فِيهِ رَسُولُ اللَّهِ ﷺ طَرَفَىِ النَّهَارِ بُكْرَةً وَعَشِيَّةً، فَبَيْنَمَا نَحْنُ جُلُوسٌ فِي بَيْتِ أَبِي بَكْرٍ فِي نَحْرِ الظَّهِيرَةِ قَالَ قَائِلٌ هَذَا رَسُولُ اللَّهِ ﷺ فِي سَاعَةٍ لَمْ يَكُنْ يَأْتِينَا فِيهَا. قَالَ أَبُو بَكْرٍ مَا جَاءَ بِهِ فِي هَذِهِ السَّاعَةِ إِلاَّ أَمْرٌ. قَالَ
" إِنِّي قَدْ أُذِنَ لِي بِالْخُرُوجِ ".
