Re: children............
During the time of the Prophet Muhammad (SAW), the most commonly practiced method of birth control was 'azl or the withdrawal method. According to the ulama (scholars), withdrawal is permissible but generally thought to be makruh (reprehensible), since it deprives the woman of her right to be able to have sexual satisfaction and to bear children if she so desires, so therefore the conclusion reached by most scholars is that withdrawal should not be practiced unless the woman agrees to it.
