Narrated `Aisha: That Allah's Messenger (ﷺ) came to her in a happy mood with his features glittering with joy, and said, "Have you not heard what the Qaif has said about Zaid and Us-ama? He saw their feet and remarked. These belong to each other." (i.e. They are father and son.)

حَدَّثَنَا يَحْيَى، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، حَدَّثَنَا ابْنُ جُرَيْجٍ، قَالَ أَخْبَرَنِي ابْنُ شِهَابٍ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم دَخَلَ عَلَيْهَا مَسْرُورًا تَبْرُقُ أَسَارِيرُ وَجْهِهِ، فَقَالَ " أَلَمْ تَسْمَعِي مَا قَالَ الْمُدْلِجِيُّ لِزَيْدٍ وَأُسَامَةَ ـ وَرَأَى أَقْدَامَهُمَا ـ إِنَّ بَعْضَ هَذِهِ الأَقْدَامِ مِنْ بَعْضٍ ".
