Quran 4:135 from Surah An-Nisaa on Divine Marvels.
۞يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ كُونُواْ قَوَّٰمِينَ بِٱلۡقِسۡطِ شُهَدَآءَ لِلَّهِ وَلَوۡ عَلَىٰٓ أَنفُسِكُمۡ أَوِ ٱلۡوَٰلِدَيۡنِ وَٱلۡأَقۡرَبِينَۚ إِن يَكُنۡ غَنِيًّا أَوۡ فَقِيرٗا فَٱللَّهُ أَوۡلَىٰ بِهِمَاۖ فَلَا تَتَّبِعُواْ ٱلۡهَوَىٰٓ أَن تَعۡدِلُواْۚ وَإِن تَلۡوُۥٓاْ أَوۡ تُعۡرِضُواْ فَإِنَّ ٱللَّهَ كَانَ بِمَا تَعۡمَلُونَ خَبِيرٗا
English translation: O you who believe[d]! Be custodians of justice (as) witnesses to Allah even if (it is) against yourselves or the parents and the relatives if he be rich or poor for Allah (is) nearer to both of them So (do) not follow the desire lest you deviate And if you distort or refrain then indeed Allah is of what you do All-Aware
