Quran 6:57 from Surah Al-An'aam on Divine Marvels.
قُلۡ إِنِّي عَلَىٰ بَيِّنَةٖ مِّن رَّبِّي وَكَذَّبۡتُم بِهِۦۚ مَا عِندِي مَا تَسۡتَعۡجِلُونَ بِهِۦٓۚ إِنِ ٱلۡحُكۡمُ إِلَّا لِلَّهِۖ يَقُصُّ ٱلۡحَقَّۖ وَهُوَ خَيۡرُ ٱلۡفَٰصِلِينَ
English translation: Say Indeed I am on clear proof from my Lord while you deny [with] it Not I have what you seek to hasten of it Not (is) the decision except for Allah He relates the truth and He (is the) best (of) the Deciders
Transliteration: qul inni ala bayyinatin min rabbi wakadhabtum bihi ma indi ma tasta'jiluna bihi ini al-huk'mu illa lillahi yaqussu al-haqa wahuwa khayru al-fasilina
