Fasting is not invalidated, whether the injection is subcutaneous, like an insulin shot, or intramuscular, or intravenous, or in any part of the outer body; because such an injection does not reach the interior through the openings considered legally – such as the mouth, nose, ear, anus, female genitalia, surgery in the head, surgery in the abdomen, and a hole if it leads to the considered interior – it only reaches through the pores, which are not considered openings, as stated in the Islamic fatwas from the Egyptian Fatwa House (1: 90), fatwa of the Grand Mufti of Egypt, Sheikh Muhammad Bekhit Al-Mut'i.
