One crucial, unequivocal verse in the Qur’an lays the ground for the concept of equality between men and women: “The believers, men and women, are allies (awliya) of one another. They enjoin the ‘common good’ (al ma‘ruf) and forbid the bad (al munkar), they observe prayers (salat) and give charitable alms (zakat) and obey God and his Prophet”; Qur’an, 9:71. Munkar refers to all that is rejected by all members of a given society; a set of morally unacceptable practices. In Qur’anic etymology it is considered as the antonym of ma‘ruf or ‘common good’.
