Quran 29:52 from Surah Al-Ankaboot on Divine Marvels.
قُلۡ كَفَىٰ بِٱللَّهِ بَيۡنِي وَبَيۡنَكُمۡ شَهِيدٗاۖ يَعۡلَمُ مَا فِي ٱلسَّمَٰوَٰتِ وَٱلۡأَرۡضِۗ وَٱلَّذِينَ ءَامَنُواْ بِٱلۡبَٰطِلِ وَكَفَرُواْ بِٱللَّهِ أُوْلَٰٓئِكَ هُمُ ٱلۡخَٰسِرُونَ
English translation: Say Sufficient is Allah between me and between you (as) Witness He knows what (is) in the heavens and the earth And those who believe in [the] falsehood and disbelieve in Allah those they (are) the losers
Transliteration: qul kafa bil-lahi bayni wabaynakum shahidan ya'lamu ma fi al-samawati wal-ardi wa-alladhina amanu bil-batili wakafaru bil-lahi ulaika humu al-khasiruna
