There are various requirements for women during their monthly period.  In addition, Muslims have a ritual cleansing in preparation for prayer and fasting where they use water and or dirt.

1. Allah loves those who keep themselves pure and clean (context of women’s menses)
   1. Surah 2:222, “They ask thee concerning women’s courses. Say: They are a hurt and a pollution: So keep away from women in their courses, and do not approach them until they are clean. But when they have purified themselves, ye may approach them in any manner, time, or place ordained for you by Allah. For Allah loves those who turn to Him constantly and He loves those who keep themselves pure and clean.”
2. Hygiene and the call of nature
   1. Face east or west when in open space
      1. “Allah’s Apostle said, “If anyone of you goes to an open space for answering the call of nature he should neither face nor turn his back towards the Qibla; he should either face the east or the west.” (Sahih Bukhari, Volume 1, Book 4, Number #146: Narrated Abu Aiyub Al-Ansari)
      2. “Once I went upstairs in Hafsa’s house and saw the Prophet answering the call of nature with his back towards the Qibla and facing Sham.” (Sahih Bukhari, Volume 4, Book 53, Number #334: Narrated ‘Abdullah bin ‘Umar)
3. Camel urine for hygiene and medicine
   1. “Some people from the tribe of ‘Ukl came to the Prophet and embraced Islam. The climate of Medina did not suit them, so the Prophet ordered them to go to the (herd of milch) camels of charity and to drink their milk and urine (as a medicine). They did so, and after they had recovered from their ailment (became healthy) they turned renegades (reverted from Islam) and killed the shepherd of the camels and took the camels away. The Prophet sent (some people) in their pursuit and so they were (caught and) brought, and the Prophets ordered that their hands and legs should be cut off and that their eyes should be branded with heated pieces of iron, and that their cut hands and legs should not be cauterized, till they die.” (Sahih Bukhari, Volume 8, Book 82, Number #794,  Narrated Anas).
4. Muhammad said that one wing of a housefly has a disease and the other wing has the cure
   1. The Prophet said “If a house fly falls in the drink of anyone of you, he should dip it (in the drink), for one of its wings has a disease and the other has the cure for the disease,” (Sahih Bukhari, Volume 4, Book 54, Number #537, Narrated Abu Huraira.)
5. Hygiene and prayer preparation
   1. Surah 5:6, “O ye who believe! When ye prepare for prayer, wash your faces, and your hands (and arms) to the elbows; Rub your heads (with water); and (wash) your feet to the ankles. If ye are in a state of ceremonial impurity, bathe your whole body. But if ye are ill, or on a journey, or one of you cometh from offices of nature, or ye have been in contact with women, and ye find no water, then take for yourselves clean sand or earth, and rub therewith your faces and hands, Allah doth not wish to place you in a difficulty, but to make you clean, and to complete his favour to you, that ye may be grateful.”
6. The tradition of personal hygiene
   1. “The Prophet said “Five things are in accordance with Al Fitra (i.e. the tradition of prophets): to be circumcised, to shave the pelvic region, to pull out the hair of the armpits, to cut short the mustaches, and to clip the nails.’ (Sahih Bukhari, Volume 8, Book 74, Number #312: Narrated Abu Huraira)
7. Mustaches to be short
   1. “Allah’s Apostle said, “Cut the mustaches short and leave the beard (as it is).” (Sahih Bukhari, Volume 7, Book 72, Number #781: Narrated Ibn ‘Umar)
8. Take a bath at least every seven days
   1. Allah’s Apostle said “We are the last (to come amongst the nations) but (will be) the foremost on the Day of Resurrection. They were given the Holy Scripture before us and we were given the quran after them. And this was the day (Friday) about which they differed and Allah gave us the guidance (for that). So tomorrow (i.e. Saturday) is the Jews’ (day), and the day after tomorrow (i.e. Sunday) is the Christians’.” The Prophet (p.b.u.h) remained silent (for a while) and then said, “It is obligatory for every Muslim that he should take a bath once in seven days, when he should wash his head and body.” Narrated Abu Huraira through different narrators that the Prophet said, “It is Allah’s right on every Muslim that he should take a bath (at least) once in seven days.”  (Sahih Bukhari, Book #13, Hadith #21, Narrated Abu Huraira)
