Surah Al-Isra — Ayah 82 (17:82)
وَنُنَزِّلُ مِنَ ٱلۡقُرۡءَانِ مَا هُوَ شِفَآءٞ وَرَحۡمَةٞ لِّلۡمُؤۡمِنِينَ وَلَا يَزِيدُ ٱلظَّٰلِمِينَ إِلَّا خَسَارٗا ٨٢
English translation (Saheeh International)
And We send down of the Qur’ān that which is healing and mercy for the believers, but it does not increase the wrongdoers except in loss.
Brief commentary
And I reveal in the Qur’ān that which cures the hearts of ignorance, disbelief and doubt, cures the bodies when treated through it, and that which is a mercy for the believers who practice it. And this Qur’ān only increases the disbelievers in destruction, as listening to it angers them and makes them deny and turn away from it even more.
