Quran 61:14 from Surah As-Saff on Divine Marvels.
يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ كُونُوٓاْ أَنصَارَ ٱللَّهِ كَمَا قَالَ عِيسَى ٱبۡنُ مَرۡيَمَ لِلۡحَوَارِيِّـۧنَ مَنۡ أَنصَارِيٓ إِلَى ٱللَّهِۖ قَالَ ٱلۡحَوَارِيُّونَ نَحۡنُ أَنصَارُ ٱللَّهِۖ فَـَٔامَنَت طَّآئِفَةٞ مِّنۢ بَنِيٓ إِسۡرَٰٓءِيلَ وَكَفَرَت طَّآئِفَةٞۖ فَأَيَّدۡنَا ٱلَّذِينَ ءَامَنُواْ عَلَىٰ عَدُوِّهِمۡ فَأَصۡبَحُواْ ظَٰهِرِينَ
