Bahishti Zewar

Ancient tome of Islamic belief written by Maulana Ashraf Ali Thanwi. It tells of various rules all good Muslims must follow, such as the well-known Five Pillars of Islam. However, it also tells of more obscure rules, such as explaining when baths are necessary to cleanse oneself:"If a mans circumcision has not been done and his semen comes out and sticks in the superfluous skin which is cut off in circumcision, then bath will be obligatory for him," and "If a man enters his penis into the back organ of a man or woman and there is no semenal discharge, then bath will not be obligatory." Ritual bathing is required after such behavior, or one may not enter a mosque. It offers instructions as well on etiquette for asking where Mecca is in order to pray in its direction and a treatise on how to milk a cow in accordance with Islam's laws, among many other things.
