Surah Al-Baqarah, ayah 138

صِبۡغَةَ ٱللَّهِ وَمَنۡ أَحۡسَنُ مِنَ ٱللَّهِ صِبۡغَةٗۖ وَنَحۡنُ لَهُۥ عَٰبِدُونَ ١٣٨

Sibghatallāhi waman ahsanu minallāhi sibghatan wanahnu lahū 'ābidūn

[And say, "Ours is] the religion of Allāh. And who is better than Allāh in [ordaining] religion? And we are worshippers of Him."
