Assalamualaikum Respected Mufti
I have a question regarding my beliefs. At times i get random thoughts like what if there is no ALLAH, or no jannat & jahannam or that islam is not the right religion. Such thoughts cause me alot of distress and i fear that i may be out of the fold of islam. When i get theses thoughts i know in my heart that it is wrong. I am regular with my salaah & try to make zikr often as well. Are these thoughts whispers from shaytaan or an act of kufr? What should i do/read to avoid such thoughts?
