Sayyiduna Abu Hurayrah (may Allah be pleased with him) said that the Prophet (peace and blessings be upon him) was in the mosque, and he (peace and blessings be upon him) said: "O Aishah! Hand me the mat." She said: I am menstruating. He (peace and blessings be upon him) said: "Your menstruation is not in your hand." So she handed it to him (peace and blessings be upon him).
