Surah Az-Zumar — Ayah 15 (39:15)
فَٱعۡبُدُواْ مَا شِئۡتُم مِّن دُونِهِۦۗ قُلۡ إِنَّ ٱلۡخَٰسِرِينَ ٱلَّذِينَ خَسِرُوٓاْ أَنفُسَهُمۡ وَأَهۡلِيهِمۡ يَوۡمَ ٱلۡقِيَٰمَةِۗ أَلَا ذَٰلِكَ هُوَ ٱلۡخُسۡرَانُ ٱلۡمُبِينُ ١٥
English translation (Saheeh International)
So worship what you will besides Him." Say, "Indeed, the losers are the ones who will lose themselves and their families on the Day of Resurrection. Unquestionably, that is the manifest loss."
Brief commentary
So you, O idolaters, worship whatever idols you wish besides Him (this instruction is a threat). Say, O Messenger:.the true losers are those who will lose themselves and their family members, whom they will not meet in the Hereafter due to them being separated in Paradise and the fire together with them. Thus they will never meet. That is indeed, and undoubtedly the obvious loss.
