Al-'Ankabut 29:52

قُلْ كَفَىٰ بِٱللَّهِ بَيْنِى وَبَيْنَكُمْ شَهِيدًا ۖ يَعْلَمُ مَا فِى ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضِ ۗ وَٱلَّذِينَ ءَامَنُوا۟ بِٱلْبَـٰطِلِ وَكَفَرُوا۟ بِٱللَّهِ أُو۟لَـٰٓئِكَ هُمُ ٱلْخَـٰسِرُونَ

Qul kafā bil-lahi baynī wabaynakum shahīdan yaʿlamu mā fī l-samāwāti wal-arḍi wa-alladhīna āmanū bil-bāṭili wakafarū bil-lahi ulāika humu l-khāsirūna

Say, "Sufficient is Allāh between me and you as Witness. He knows what is in the heavens and earth. And they who have believed in falsehood and disbelieved in Allāh - it is those who are the losers."
