Surah Al-Hajj Verse 11

وَمِنَ النَّاسِ مَن يَعْبُدُ اللَّهَ عَلَىٰ حَرْفٍ ۖ فَإِنْ أَصَابَهُ خَيْرٌ اطْمَأَنَّ بِهِ ۖ وَإِنْ أَصَابَتْهُ فِتْنَةٌ انقَلَبَ عَلَىٰ وَجْهِهِ خَسِرَ الدُّنْيَا وَالْآخِرَةَ ۚ ذَٰلِكَ هُوَ الْخُسْرَانُ الْمُبِينُ

Wa minan naasi mai ya'budul laaha 'alaa harfin fa in asaabahoo khairunit maanna bihee wa in asaabat hu fitnatunin qalaba 'alaa wajhihee khasirad dunyaa wal aakhirah; zaalika huwal khusraanul mubeen

Translation / The Meaning

And of the people is he who worships Allah on an edge. If he is touched by good, he is reassured by it; but if he is struck by trial, he turns on his face [to the other direction]. He has lost [this] world and the Hereafter. That is what is the manifest loss.
