Answered by Shaykh Faraz Rabbani
Can one do ghusl over a birth control patch as it is not exactly “necessary” and the pill is an alternative, albeit a less desired one?
Answer:
In the Name of Allah, Most Merciful and Compassionate
May Allah’s peace and blessings be upon His Messenger Muhammad, his folk, companions, and followers
Walaikum assalam wa rahmatullah,
A birth control patch is considered a form of “medical treatment,” and would take the ruling of other patches or bandages: when there is harm or hardship in removing them then one can simply wipe over them with a wetted hand such that one wipes most of the area; when this is not possible without reasonable fear of harm, then one can leave wiping them, and it will not affect the validity of one’s ritual ablution or bath. [Ibn Abidin, Radd al-Muhtar; Shurunbulali, Imdad al-Fattah]
And Allah alone gives success.
Wassalam,
