قٰلَ رَبِّ احْكُمْ بِالْحَقِّ وَرَبُّنَا الرَّحْمٰنُ الْمُسْتَعَانُ عَلٰی مَا تَصِفُوْنَ 

Qaala Rabbih kum bil haqq; wa Rabbunar Rahmaa nul musta'aanu 'alaa maa tasifoon

“Say: "O my Lord! judge Thou in truth!" "Our Lord Most Gracious is the One Whose assistance should be sought against the blasphemies ye utter!"”
