Sahih al-Bukhari 4573
Narrated Aisha:
There was an orphan (girl) under the care of a man. He married her and she owned a date palm 
(garden). He married her just because of that and not because he loved her. So the Divine Verse came 
regarding his case: "If you fear that you shall not be able to deal justly with the orphan girls..." (4.3) 
The sub-narrator added: I think he (i.e. another sub-narrator) said, "That orphan girl was his partner in 
that datepalm (garden) and in his property."
حَدَّثَنَا إِبْرَاهِيمُ بْنُ مُوسَى، أَخْبَرَنَا هِشَامٌ، عَنِ ابْنِ جُرَيْجٍ، قَالَ أَخْبَرَنِي هِشَامُ بْنُ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ أَنَّ رَجُلاً، كَانَتْ لَهُ يَتِيمَةٌ فَنَكَحَهَا، وَكَانَ لَهَا عَذْقٌ، وَكَانَ يُمْسِكُهَا عَلَيْهِ، وَلَمْ يَكُنْ لَهَا مِنْ نَفْسِهِ شَىْءٌ فَنَزَلَتْ فِيهِ ‏{‏وَإِنْ خِفْتُمْ أَنْ لاَ تُقْسِطُوا فِي الْيَتَامَى‏}‏ أَحْسِبُهُ قَالَ كَانَتْ شَرِيكَتَهُ فِي ذَلِكَ الْعَذْقِ وَفِي مَالِهِ‏.‏
