فَإِنْ أَعْرَضُوا۟ فَمَآ أَرْسَلْنَٰكَ عَلَيْهِمْ حَفِيظًا ۖ إِنْ عَلَيْكَ إِلَّا ٱلْبَلَٰغُ ۗ وَإِنَّآ إِذَآ أَذَقْنَا ٱلْإِنسَٰنَ مِنَّا رَحْمَةًۭ فَرِحَ بِهَا ۖ وَإِن تُصِبْهُمْ سَيِّئَةٌۢ بِمَا قَدَّمَتْ أَيْدِيهِمْ فَإِنَّ ٱلْإِنسَٰنَ كَفُورٌۭ
But if they are averse, We have not sent thee as a warder over them. Thine is only to convey (the message). And lo! when We cause man to taste of mercy from Us he exulteth therefor. And if some evil striketh them because of that which their own hands have sent before, then lo! man is an ingrate.
Surah Ash-Shura(42:48)
