Quran 5:116 from Surah Al-Maaida on Divine Marvels.
وَإِذۡ قَالَ ٱللَّهُ يَٰعِيسَى ٱبۡنَ مَرۡيَمَ ءَأَنتَ قُلۡتَ لِلنَّاسِ ٱتَّخِذُونِي وَأُمِّيَ إِلَٰهَيۡنِ مِن دُونِ ٱللَّهِۖ قَالَ سُبۡحَٰنَكَ مَا يَكُونُ لِيٓ أَنۡ أَقُولَ مَا لَيۡسَ لِي بِحَقٍّۚ إِن كُنتُ قُلۡتُهُۥ فَقَدۡ عَلِمۡتَهُۥۚ تَعۡلَمُ مَا فِي نَفۡسِي وَلَآ أَعۡلَمُ مَا فِي نَفۡسِكَۚ إِنَّكَ أَنتَ عَلَّٰمُ ٱلۡغُيُوبِ
