Quran 22:11 from Surah Al-Hajj on Divine Marvels.
وَمِنَ ٱلنَّاسِ مَن يَعۡبُدُ ٱللَّهَ عَلَىٰ حَرۡفٖۖ فَإِنۡ أَصَابَهُۥ خَيۡرٌ ٱطۡمَأَنَّ بِهِۦۖ وَإِنۡ أَصَابَتۡهُ فِتۡنَةٌ ٱنقَلَبَ عَلَىٰ وَجۡهِهِۦ خَسِرَ ٱلدُّنۡيَا وَٱلۡأٓخِرَةَۚ ذَٰلِكَ هُوَ ٱلۡخُسۡرَانُ ٱلۡمُبِينُ
English translation: And among the mankind (is he) who worships Allah on an edge And if befalls him good he is content with it and if befalls him a trial he turns on his face He has lost the world and the Hereafter That [it] (is) the loss clear
