Female medical treatment in Ramadan
Answered by Shaykh Faraz Rabbani
She had to insert an instrument and also I think her fingers to check where my injuries are inside. Did this break my fast?
Mere insertion of the finger or an instrument in the vagina does not invalidate the fast, unless it is wetted with water or oil [or any other substance that will remain within]. (Ibn al-Humam, Fath al-Qadir, a commentary on Marghinanis Hidaya)
And Allah alone gives success.
