[Machine] The Prophet ﷺ married her before leaving Mecca for Medina, when she was three years old, or close to that. He consummated the marriage when she was six years old. After his arrival in Medina and when she was nine years old, he built a marital relationship with her.
أَنَّ النَّبِيَّ ﷺ «تَزَوَّجَهَا قَبْلَ مَخْرَجِهِ مِنْ مَكَّةَ بِثَلَاثِ سِنِينَ أَوْ قَرِيبًا مِنْ ذَلِكَ وَنَكَحَهَا وَهِيَ بِنْتُ سِتِّ سِنِينَ ثُمَّ بَنَى بِهَا بَعْدَ مَقْدَمِهِ الْمَدِينَةَ وَهِيَ يَوْمَ بِنَائِهَا بِنْتُ تِسْعٍ»
