Karimah, daughter of Hammam, told that a woman came to Aisha (Allah be pleased with her) and asked her about dyeing with henna. She replied: There is no harm, but I do not like it. My beloved, the Messenger of Allah ﷺ, disliked its odour. Abu Dawud said: She meant the colour of hair of the head.  

أَنَّ امْرَأَةً أَتَتْ عَائِشَةَ ؓ فَسَأَلَتْهَا عَنْ خِضَابِ الْحِنَّاءِ فَقَالَتْ لاَ بَأْسَ بِهِ وَلَكِنِّي أَكْرَهُهُ كَانَ حَبِيبِي رَسُولُ اللَّهِ ﷺ يَكْرَهُ رِيحَهُ  

When Hind, daughter of Utbah, said: Prophet of Allah, accept my allegiance, he replied; I shall not accept your allegiance till you make a difference to the palms of your hands; for they look like the paws of a beast of prey.  

يَا نَبِيَّ اللَّهِ بَايِعْنِي قَالَ لاَ أُبَايِعُكِ حَتَّى تُغَيِّرِي كَفَّيْكِ كَأَنَّهُمَا كَفَّا سَبُعٍ  

A woman made a sign from behind a curtain to indicate that she had a letter for the Messenger of Allah ﷺ. The Prophet ﷺ closed his hand, saying: I do not know this is a man's or a woman's hand. She said: No, a woman. He said: If you were a woman, you would make a difference to your nails, meaning with henna.  

أَوْمَتِ امْرَأَةٌ مِنْ وَرَاءِ سِتْرٍ بِيَدِهَا كِتَابٌ إِلَى رَسُولِ اللَّهِ ﷺ فَقَبَضَ النَّبِيُّ ﷺ يَدَهُ فَقَالَ مَا أَدْرِي أَيَدُ رَجُلٍ أَمْ يَدُ امْرَأَةٍ قَالَتْ بَلِ امْرَأَةٌ قَالَ لَوْ كُنْتِ امْرَأَةً لَغَيَّرْتِ أَظْفَارَكِ يَعْنِي بِالْحِنَّاءِ
