قُلۡ كَفَىٰ بِٱللَّهِ بَيۡنِي وَبَيۡنَكُمۡ شَهِيدٗاۖ يَعۡلَمُ مَا فِي ٱلسَّمَٰوَٰتِ وَٱلۡأَرۡضِۗ وَٱلَّذِينَ ءَامَنُواْ بِٱلۡبَٰطِلِ وَكَفَرُواْ بِٱللَّهِ أُوْلَٰٓئِكَ هُمُ ٱلۡخَٰسِرُونَ

Qul kafaa billaahi bainee wa bainakum shaheedaa; ya'lamu maa fis samaawaati wal ard; wallazeena aamanoo bil baatili wa kafaroo billaahi ulaaa'ika humul khaasiroon

Say: "Enough is Allah for a witness between me and you: He knows what is in the heavens and on earth. And it is those who believe in vanities and reject Allah, that will perish (in the end).

— Al-Ankabut (ٱلْعَنْكَبُوت), 29:52
