2:138
صِبْغَةَ ٱللَّهِ ۖ وَمَنْ أَحْسَنُ مِنَ ٱللَّهِ صِبْغَةً ۖ وَنَحْنُ لَهُۥ عَـٰبِدُونَ
ṣib'ghata l-lahi waman aḥsanu mina l-lahi ṣib'ghatan wanaḥnu lahu ʿābidūna
‘[Our life] takes its colour from God, and who gives a better colour than God? It is Him we worship.’
[Our Sibghah (religion) is] the Sibghah (Religion) of Allâh (Islâm) and which Sibghah (religion) can be better than Allâh’s? And we are His worshippers. [Tafsir Ibn Kathîr]
