Mishkat al-Masabih #3123
Marriage
The Arabic includes the chain of narration (sanad) and the collector's commentary; the English translation shows the Prophet's words only.
عَن عَائِشَة رَضِي الله عَنْهَا أَنَّهَا كَانَتْ مَعَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي سَفَرٍ قَالَتْ: فَسَابَقْتُهُ فَسَبَقْتُهُ عَلَى رِجْلَيَّ فَلَمَّا حَمَلْتُ اللَّحْمَ سَابَقْتُهُ فَسَبَقَنِي قَالَ: «هَذِهِ بِتِلْكَ السَّبْقَةِ» . رَوَاهُ أَبُو دَاوُدَ
'A'isha told that when she was with God's Messenger on a journey she raced him on foot and beat him, but when she grew she raced him and he beat her. He said, “This makes up for that beating."
Abu Dawud transmitted it.
