Verse 11

وَمِنَ ٱلنَّاسِ مَن يَعْبُدُ ٱللَّهَ عَلَىٰ حَرْفٍ فَإِنْ أَصَابَهُۥ خَيْرٌ ٱطْمَأَنَّ بِهِۦ وَإِنْ أَصَابَتْهُ فِتْنَةٌ ٱنقَلَبَ عَلَىٰ وَجْهِهِۦ خَسِرَ ٱلدُّنْيَا وَٱلْـَٔاخِرَةَ ذَٰلِكَ هُوَ ٱلْخُسْرَانُ ٱلْمُبِينُ

And amongst the people are those who worship God conditionally. If something good happens to him he is secure but once he is tested, he turns about face, a loss in this world as well as the Hereafter. This is the manifest loss.
