Surah 13. Ar Ra'd - Ayah 27-28 And those who disbelieve say: "Why is not a sign sent down to him from his Lord?" Say: "Verily, Allaah sends astray whom He wills and guides unto Himself those who turn to Him in repentance."
Those who believe, and whose hearts find rest in the remembrance of Allaah, Verily, in the remembrance of Allaah do hearts find rest.
