Hadith 1356
Sayyida Aisha Siddiqa (may Allah be pleased with her) narrates: The Prophet Muhammad (peace be upon him) said to a slave girl: Hand me the prayer mat. The intention of the Prophet (peace be upon him) was to spread it out and pray on it. I said: She is in the state of menstruation. The Prophet (peace be upon him) said: Her menstruation is not in her hand.
