(as regards the Verse): 'And about what is recited unto you in the Book, concerning orphan girls to whom you give not the prescribed portions and yet, whom you desire to marry.' (4.127) This Verse is about the female orphan who is under the guardianship of a man with whom she shares her property and he has more right over her (than anybody else) but does not like to marry her, so he prevents her, from marrying somebody else, lest he should share the property with him. (Using translation from Bukhārī 5128)   

ؓ {وَمَا يُتْلَى عَلَيْكُمْ فِي الْكِتَابِ فِي يَتَامَى النِّسَاءِ اللَّاتِي لَا تُؤْتُونَهُنَّ مَا كُتِبَ لَهُنَّ وَتَرْغَبُونَ أَنْ تَنْكِحُوهُنَّ} [النساء 127] قَالَتْ هَذِهِ الْيَتِيمَةُ تَكُونُ عِنْدَ الرَّجُلِ هُوَ وَلِيُّهَا لَعَلَّهَا تَكُونُ شَرِيكَتَهُ فِي مَالِهِ وَهُوَ أَوْلَى بِهَا فَيَرْغَبُ عَنْهَا أَنْ يَنْكِحَهَا وَيَعْضِلُهَا لِمَا لَهَا فَلَا يُنْكِحُهَا غَيْرَهُ كَرَاهِيَةَ أَنْ يَشْرَكَهُ أَحَدٌ فِي مَالِهِ
