Sahih al-Bukhari 62:78
Narrated `Urwa:
Aisha said, "A Qaif (i.e. one skilled in recognizing the lineage of a person through Physiognomy and through examining the body parts of an infant) came to me while the Prophet (ﷺ) was present, and Usama bin Zaid and Zaid bin Haritha were Lying asleep. The Qa'if said. These feet (of Usama and his father) are of persons belonging to the same lineage.' " The Prophet (ﷺ) was pleased with that saying which won his admiration, and he told `Aisha of it.

حَدَّثَنَا يَحْيَى بْنُ قَزَعَةَ، حَدَّثَنَا إِبْرَاهِيمُ بْنُ سَعْدٍ، عَنِ الزُّهْرِيِّ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ دَخَلَ عَلَىَّ قَائِفٌ وَالنَّبِيُّ صلى الله عليه وسلم شَاهِدٌ، وَأُسَامَةُ بْنُ زَيْدٍ وَزَيْدُ بْنُ حَارِثَةَ مُضْطَجِعَانِ، فَقَالَ إِنَّ هَذِهِ الأَقْدَامَ بَعْضُهَا مِنْ بَعْضٍ. قَالَ فَسُرَّ بِذَلِكَ النَّبِيُّ صلى الله عليه وسلم وَأَعْجَبَهُ، فَأَخْبَرَ بِهِ عَائِشَةَ.
