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.
Sunan Abi Dawud Book 35, Hadith 7
← Previous Hadith 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.

Sunan Abi Dawud Book 35, Hadith 6 Next Hadith → 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.
