Quran 42:48 from Surah Ash-Shura on Divine Marvels.
فَإِنۡ أَعۡرَضُواْ فَمَآ أَرۡسَلۡنَٰكَ عَلَيۡهِمۡ حَفِيظًاۖ إِنۡ عَلَيۡكَ إِلَّا ٱلۡبَلَٰغُۗ وَإِنَّآ إِذَآ أَذَقۡنَا ٱلۡإِنسَٰنَ مِنَّا رَحۡمَةٗ فَرِحَ بِهَاۖ وَإِن تُصِبۡهُمۡ سَيِّئَةُۢ بِمَا قَدَّمَتۡ أَيۡدِيهِمۡ فَإِنَّ ٱلۡإِنسَٰنَ كَفُورٞ
English translation: Then if they turn away then not We have sent you over them (as) a guardian Not (is) on you except the conveyance And indeed when We cause to taste [the] man from Us Mercy he rejoices in it But if befalls them evil for what have sent forth their hands then indeed [the] man (is) ungrateful
Transliteration: fa-in a'radu fama arsalnaka alayhim hafizan in alayka illa al-balaghu wa-inna idha adhaqna al-insana minna rahmatan fariha biha wa-in tusib'hum sayyi-atun bima qaddamat aydihim fa-inna al-insana kafurun
