It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him), he says: A Bedouin came to the Noble Prophet (peace and blessings be upon him) and said: O Messenger of Allah! I remain in the desert for four or five months, and among us are women in postnatal bleeding and menstruation, and people in a state of major ritual impurity (janabah). What is your opinion regarding this? The Prophet (peace and blessings be upon him) said: Then adhere to the use of earth (i.e., perform tayammum).
