Does drawing blood via injection break Wudu or not?
If blood is drawn via injection for a test or any other purpose, it will break the Wudu, because usually for a test, that much blood is drawn which can flow after coming out from its place. But if an injection is given for the purpose of administering medicine, then this injection does not break Wudu. Yes, if after getting the injection, that much blood comes out which can flow from its place, then it will break Wudu. (Aham Masail / Vol: 2 / Pg: 59)
