Menstruation in Islam relates to various purity related restrictions in Islamic jurisprudence. The ḥayḍ (Arabic: حيض) is the religious state of menstruation in Islam. The Qur'an makes specific mention of menstruation in al-Baqara 2:222:
The language is taken to imply that sexual relations during menstruation are prohibited.
Ramadan is the ninth month of the Islamic calendar. It is observed by Muslims worldwide as a month of fasting (sawm), communal prayer (salah), reflection, and community. It is also the month in which the Quran is believed to have been revealed to the Islamic prophet Muhammad. The annual observance of Ramadan is regarded as one of the five pillars of Islam and lasts twenty-nine to thirty days, from one sighting of the crescent moon to the next.
Fasting from dawn to sunset is obligatory (fard) for all adult Muslims who are not acutely or chronically ill, travelling, elderly, breastfeeding, pregnant, or menstruating. The predawn meal is referred to as suhur, and the nightly feast that breaks the fast is called iftar. Although rulings (fatawa) have been issued declaring that Muslims who live in regions with a midnight sun or polar night should follow the timetable of Mecca, it is common practice to follow the timetable of the closest country in which night can be distinguished from day.
