وَحَدَّثَنَا الْحَسَنُ الْحُلْوَانِىُّ وَعَبْدُ بْنُ حُمَيْدٍ جَمِيعًا عَنْ يَعْقُوبَ بْنِ إِبْرَاهِيمَ بْنِ سَعْدٍ حَدَّثَنَا أَبِى عَنْ صَالِحٍ عَنِ ابْنِ شِهَابٍ أَخْبَرَنِى عُرْوَةُ أَنَّهُ سَأَلَ عَائِشَةَ عَنْ قَوْلِ اللَّهِ (وَإِنْ خِفْتُمْ أَنْ لاَ تُقْسِطُوا فِى الْيَتَامَى) وَسَاقَ الْحَدِيثَ بِمِثْلِ حَدِيثِ يُونُسَ عَنِ الزُّهْرِىِّ وَزَادَ فِى آخِرِهِ مِنْ أَجْلِ رَغْبَتِهِمْ عَنْهُنَّ إِذَا كُنَّ قَلِيلاَتِ الْمَالِ وَالْجَمَالِ.

'Urwah narrated that he asked 'Aishah about the Verse in which Allah, Blessed and Exalted is He, said: "And if you fear that you shall not be able to deal justly with the orphan girls..." And he narrated a Hadith like that of Yunus from Az-Zuhri (no. 7528), at the end of which he added: "Because they would not like to marry them if they had little in the way of wealth and beauty."
