10 Preface في قُلوبِهِم مَرَضٌ فَزادَهُمُ اللَّهُ مَرَضًا ۖ وَلَهُم عَذابٌ أَليمٌ بِما كانوا يَكذِبونَYusuf AliIn their hearts is a disease; and God has increased their disease1: And grievous is the penalty they (incur), because they are false (to themselves).The insincere man who thinks he can get the best of both worlds by compromising with good and evil only increases the disease of his heart, because he is not true to himself. Even the good which comes to him he can pervert to evil. So the rain which fills out the ear of corn or lends fragrance to the rose also lends strength to the thorn or adds strength to the poison of the deadly nightshade. (Cf. 9:125 and n. 1376).
