﴿وَنُنَزِّلُ مِنَ الْقُرْآنِ مَا هُوَ شِفَاءٌ وَرَحْمَةٌ لِلْمُؤْمِنِينَ ۙ وَلَا يَزِيدُ الظَّالِمِينَ إِلَّا خَسَارًا﴾
82. And We send down of the Qur’ân that which is a healing and a mercy to those who believe (in Islâmic Monotheism and act on it), and it increases the Zâlimûn (polytheists and wrong-doers) nothing but loss.
