فَاعْبُدُوا مَا شِئْتُم مِّن دُونِهِ قُلْ إِنَّ الْخَاسِرِينَ الَّذِينَ خَسِرُوا أَنفُسَهُمْ وَأَهْلِيهِمْ يَوْمَ الْقِيَامَةِ أَلَا ذَلِكَ هُوَ الْخُسْرَانُ الْمُبِينُ
You worship whatever you wish besides Him.’ Say, ‘The losers are those who ruin themselves and their families on the Day of Resurrection.’ Indeed, that is a manifest loss!
Agha Ali Puya Commentary
Commentary on Quran 39:15
[Pooya/Ali Commentary 39:15] This is not a command or permission but a reproach and warning. He who gains the whole world and loses his own soul shall not be profited. He has given his soul in exchange of that which will surely land him in the midst of eternal damnation, because clear guidance came to him but he chose to go astray.
