Sahih Muslim Book - 54, Hadith - 7531

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِى شَيْبَةَ حَدَّثَنَا عَبْدَةُ بْنُ سُلَيْمَانَ عَنْ هِشَامٍ عَنْ أَبِيهِ عَنْ عَائِشَةَ فِى قَوْلِهِ ( وَمَا يُتْلَى عَلَيْكُمْ فِى الْكِتَابِ فِى يَتَامَى النِّسَاءِ اللاَّتِى لاَ تُؤْتُونَهُنَّ مَا كُتِبَ لَهُنَّ وَتَرْغَبُونَ أَنْ تَنْكِحُوهُنَّ) قَالَتْ أُنْزِلَتْ فِى الْيَتِيمَةِ تَكُونُ عِنْدَ الرَّجُلِ فَتَشْرَكُهُ فِى مَالِهِ فَيَرْغَبُ عَنْهَا أَنْ يَتَزَوَّجَهَا وَيَكْرَهُ أَنْ يُزَوِّجَهَا غَيْرَهُ فَيَشْرَكُهُ فِى مَالِهِ فَيَعْضِلُهَا فَلاَ يَتَزَوَّجُهَا وَلاَ يُزَوِّجُهَا غَيْرَهُ.

It was narrated from 'Aishah concerning the Verse, "...And about what is recited unto you in the Book concerning the orphan girls whom you give not the prescribed portions (as regards dowry and inheritance) and yet whom you desire to marry..."' - that she said: "It was revealed concerning an orphan girl who is in the care of a man, and she shares in his wealth, and he is reluctant to marry her himself, but he does not want to give her in marriage to someone else who will share his wealth. So he prevents her from marrying, and he does not marry her himself nor give her in marriage to someone else."
