,السلام علیکم و رحمة الله و بركاته Is it mubah, haraam, or makrooh to go to a Kafir Doctor when a Muslim doctor in that specialty is available in matters not affecting religion? What if a Muslim doctor of only the opposite gender is available? !بارك الله فيك وأكرمك أستاذ

Ustadh AbdulAziz al-Haqqan
If it is a trustworthy female doctor for example who is not a Muslim and u want to take your female relative to, no prpblem in sha'a Allah
