Narrated Aisha, Ummul Mu'minin:

while she was on a journey along with the Messenger of Allah ﷺ: I had a race with him (the Prophet) and I outstripped him on my feet. When I became fleshy, (again) I had a race with him (the Prophet) and he outstripped me. He said: This is for that outstripping.

حَدَّثَنَا أَبُو صَالِحٍ الأَنْطَاكِيُّ، مَحْبُوبُ بْنُ مُوسَى أَخْبَرَنَا أَبُو إِسْحَاقَ، - يَعْنِي الْفَزَارِيَّ - عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، وَعَنْ أَبِي سَلَمَةَ، عَنْ عَائِشَةَ، رَضِيَ اللَّهُ عَنْهَا أَنَّهَا كَانَتْ مَعَ النَّبِيِّ ﷺ فِي سَفَرٍ قَالَتْ فَسَابَقْتُهُ فَسَبَقْتُهُ عَلَى رِجْلَىَّ فَلَمَّا حَمَلْتُ اللَّحْمَ سَابَقْتُهُ فَسَبَقَنِي فَقَالَ " هَذِهِ بِتِلْكَ السَّبْقَةِ " .
