Quran 2:64 from Surah Al-Baqara on Divine Marvels.
ثُمَّ تَوَلَّيۡتُم مِّنۢ بَعۡدِ ذَٰلِكَۖ فَلَوۡلَا فَضۡلُ ٱللَّهِ عَلَيۡكُمۡ وَرَحۡمَتُهُۥ لَكُنتُم مِّنَ ٱلۡخَٰسِرِينَ
English translation: Then you turned away from after that So if not (for the) Grace (of) Allah upon you and His Mercy surely you would have been of the losers
Transliteration: thumma tawallaytum min ba'di dhalika falawla fadlu al-lahi alaykum warahmatuhu lakuntum mina al-khasirina
