Regarding the rulings of birth control, withdrawal, taking birth together, kissing the wife’s body by the husband, fingering the wife and oral sex, Dr. Main K. Al-Qudah responded as thus:
Firstly, using any birth control upon a mutual consent of the spouses, as long as it is not a permanent method to prevent birth in the future, and as long as it does not have serious side effect is permissible.
Secondly, coitus interrupts or withdrawal is allowed, and whether in the first night of marriage or afterward.
Thirdly, it is allowed for spouses to jointly have a shower. It was authentically narrated by `A’ishah (may Allah be pleased with her) that she did bathe herself with the Prophet (peace and blessings be upon him) at the same time.
However, having intercourse while having a shower might not be recommended from a medical point of view because of the possible infection- especially for the wife- caused by the unintentional inserting of some hygiene liquids into her vagina while having intercourse.
Fourthly, all of a wife’s body could be kissed by her husband upon mutual consent.
Sixthly, it is permissible to finger wife’s vagina, and it could be recommended if this will help the wife having her orgasm or sexual climax.
Seventhly, Oral sex is permissible if the spouses would like to do so.’
