The exegete, researcher and scholar of the holy Quran talked about the damages of not having peace of mind and thinking comfort and said: according to Holy Quran, the one who doesn’t have peace of mind, calmness and thinking comfort and flies off the handle and shrieks for no good reason and rants and raves about the Lord of the universe that why he is not bringing good fortune in his life and causing misery and sufferings instead, is also storing fires for his hereafter.
