Assalamualikum Mufti Saheb.
Currently there are alot of things going on in my mind, Mainly the fear to lose my Imaan and islam. Everything i do or say comes back to my mind and I feel as if i lost my imaan and out of the folds of Islam. This is really disturbing me a lot. My question is when exactly does one fall out of the folds of islam? Also all funny thoughts are coming in my mind. A while back the thought of changing religions suddenly came into mind. I can not remember exactly what my mental reaction was but verbally i did not say anything. Also one i might have propagated wrong unintentionally without doing proper research. I have this constant fear all the time of llosing my imaan and falling out of the folds of islam. How can I increase my imaan?
Also can a muslim ask a non muslim to make duaa for him?
