Fasting ( sawm ): Fasting is obligatory for every a mukallaf , who has come of age and does not have a valid exception. One must fast during the month of Ramadān in every year. It is also recommended to fast on other days throughout the year, except on the two holy days (‛ īd ), for it is forbidden to fast on those days. It is not recommended to fast on the tenth day of the month of Muharram .
A fasting person must refrain from eating, drinking, sexual intercourse, soaking the head in water, inhaling thick smoky substances…etc. Staying in a mosque ( i‛tikāf ): The Arabic term i‛tikāf literally means staying in a specific place, but when used as a jurisprudential term it means staying for an extended time in a mosque in order to worship. This is an act of worship that a person does by fasting for three or more days in a mosque.
The different rules and conditions of this are explained in jurisprudence. I‛tikāf is essentially recommended, but if one performs i‛tikāf for two days, the third day becomes obligatory. One must perform this act of worship in the Holy Mosque of Mecca, the Prophet's Mosque in Medina, the Kufa Mosque, The Basra Mosque, or, at least, the main congregational mosque of a city. One may not perform this act in a small mosque.
The Prophet (s) would perform i‛tikāf on the last ten days of the month of Ramadān . Pilgrimage ( hajj ): The Arabic term hajj literally means intention, but in jurisprudence it is a term which comprises of different actions performed in a specified place (Mecca and its surroundings). It is obligatory on anyone who meets all of the conditions.
