The Prophet ﷺ said: If anyone has a female child, and does not bury her alive, or slight her, or prefer his children (i.e. the male ones) to her, Allah will bring him into Paradise. Uthman did not mention "male children".  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ كَانَتْ لَهُ أُنْثَى فَلَمْ يَئِدْهَا وَلَمْ يُهِنْهَا وَلَمْ يُؤْثِرْ وَلَدَهُ عَلَيْهَا قَالَ يَعْنِي الذُّكُورَ أَدْخَلَهُ اللَّهُ الْجَنَّةَ وَلَمْ يَذْكُرْ عُثْمَانُ يَعْنِي الذُّكُورَ  

The Prophet ﷺ said: If anyone cares for three daughters, disciplines them, marries them, and does good to them, he will go to Paradise.  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ عَالَ ثَلاَثَ بَنَاتٍ فَأَدَّبَهُنَّ وَزَوَّجَهُنَّ وَأَحْسَنَ إِلَيْهِنَّ فَلَهُ الْجَنَّةُ  

“three sisters, or three daughter, or two daughter, or two sisters”.  

ثَلاَثُ أَخَوَاتٍ أَوْ ثَلاَثُ بَنَاتٍ أَوْ بِنْتَانِ أَوْ أُخْتَانِ  

The Prophet ﷺ said: I and a woman whose cheeks have become black shall on the Day of Resurrection be like these two (pointing to the middle and forefinger), i.e. a woman of rank and beauty who has been bereft of her husband and devotes herself to her fatherless children till they go their separate ways or die.  

قَالَ رَسُولُ اللَّهِ ﷺ أَنَا وَامْرَأَةٌ سَفْعَاءُ الْخَدَّيْنِ كَهَاتَيْنِ يَوْمَ الْقِيَامَةِ وَأَوْمَأَ يَزِيدُ بِالْوُسْطَى وَالسَّبَّابَةِ امْرَأَةٌ آمَتْ مِنْ زَوْجِهَا ذَاتُ مَنْصِبٍ وَجَمَالٍ حَبَسَتْ نَفْسَهَا عَلَى يَتَامَاهَا حَتَّى بَانُوا أَوْ مَاتُوا
