In contrast to Christian and Jewish traditions, from earliest times family planning and contraception found acceptance in Islamic tradition. The Quran contains no clear or explicit text regarding birth control. However, the traditions (hadith) of Muhammad do. Though some traditions forbid birth control, the majority permit it. The vast majority of Sunni and Shii jurists believed that birth control through use of coitus interruptus (azl) was permissible, although a minority disagreed. However, because this procedure deprived a woman of her rights to children and to sexual satisfaction, her consent was required. Sunni and Shii jurists, employing the legal principle of reasoning by analogy (qiyas), have argued that since birth control in the form of coitus interruptus has been accepted for so long in Islam, then by analogy other, more modern forms of birth control such as use of the diaphragm, contraceptive pill, and IUD are acceptable.
