Hazrat Aisha (may Allah be pleased with her) narrates that the Messenger of Allah (peace and blessings be upon him) would extend his blessed head towards me while I was in the state of menstruation and he was in the state of i'tikaf. Then the Messenger of Allah (peace and blessings be upon him) would place his blessed head in my lap and I would wash and comb his hair while I was in the state of menstruation.

Hazrat Mughira says that Hazrat Abu Zubyan asked Ibrahim whether a menstruating woman can help a sick person perform ablution. He replied that there is no harm in it.

Hasan says that there is no harm if a menstruating woman washes a man's head and combs his hair.

The mother of Hazrat Manbooz says that Hazrat Ibn Abbas (may Allah be pleased with them) came to Hazrat Maymunah. She said, "O my son! What is the matter? I see your hair in a disheveled state." He replied, "The one who combs my hair, Umm Ammar, is in a state of menstruation." Hazrat Maymunah said, "O my son! Is menstruation in the hand?" The Messenger of Allah (peace and blessings be upon him) used to place his blessed head in the lap of one of us even though she was menstruating.

Hazrat Zuhri says that if a sick person does not have the strength to perform ablution, he should perform tayammum.

Hazrat Saeed bin Jubair and Hazrat Mujahid, regarding the sick person who becomes junub and fears harm from bathing, state that he is in the same position as a traveler who does not find water and should perform tayammum. Hazrat Qais says that he asked Hazrat Ata about this, and he replied that the use of water is necessary, even if it is used after heating.
