Ive been trying to read the Quran daily and usually read Surah mulk and waqiah. Today I tried reading surah ar Rahman with the intention of marriage and halfway through had a really bad headache, nausea and the urge to vomit. I could taste blood in my mouth and in my nose and I started shaking and stuttering over the words and sweating. I know this is not normal but is this a sign of black magic or nazar, or should I get it checked out medically?
