Quran 22, Al-Hajj (The Pilgrimage) ⓘ
22:11And among mankind is he who worshippeth Allah upon a narrow marge so that if good befalleth him he is content therewith, but if a trial befalleth him, he falleth away utterly. He loseth both the world and the Hereafter. That is the sheer loss.
وَمِنَ النَّاسِ مَنْ يَعْبُدُ اللَّهَ عَلَى حَرْفٍ فَإِنْ أَصَابَهُ خَيْرٌ اطْمَأَنَّ بِهِ وَإِنْ أَصَابَتْهُ فِتْنَةٌ انْقَلَبَ عَلَى وَجْهِهِ خَسِرَ الدُّنْيَا وَالْآخِرَةَ ذَلِكَ هُوَ الْخُسْرَانُ الْمُبِينُ
