Respected Hakeem Sahib Assalamoalaikum! May Allah Almighty grant you more knowledge, Ameen. This is my small experience that when doctors are giving any one injection than recite this 3 times and InshAllah, one will not get its rection or side effects, it is my personal experience.

بِسْمِ اللہِ الرَّحْمٰنِ الرَّحِیْمِ۔ بِسْمِ اللہِ الَّذِیْ لَایَضُرُّ مَعَ اسْمِہٖ شَئْیٌ فِی الْاَرْضِ وَلَآ فِی السَّمَآءِ وَھُوَالسَّمِیْعُ الْعَلِیْم کم
