Al-Isra 17:82

Wanunazzilu mina alqur-ani mahuwa shifaon warahmatun lilmu/mineena walayazeedu aththalimeena illakhasara

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.

We reveal the Qur’ān, which is cure and mercy for the believers; and it adds nothing to the unjust but loss.
