Narrated Aisha (RA) , Ummul Muminin (RA) : 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 mans or a womans hand. She said: No, a woman. He said: If you were a woman, you would make a difference to your nails, meaning with henna.
