Surat Al-Israa (The Night Journey) - الإسراء

وَنُنَزِّلُ مِنَ ٱلْقُرْءَانِ مَا هُوَ شِفَآءٌ وَرَحْمَةٌ لِّلْمُؤْمِنِينَ وَلَا يَزِيدُ ٱلظَّٰلِمِينَ إِلَّا خَسَارًا ﴿٨٢﴾

And We reveal of the Quran that which is a healing and a mercy to the believers, and it adds only to the perdition of the unjust.
