Surah As-Saff, Verse 14
يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ كُونُوٓا۟ أَنصَارَ ٱللَّهِ كَمَا قَالَ عِيسَى ٱبْنُ مَرْيَمَ لِلْحَوَارِيِّۦنَ مَنْ أَنصَارِىٓ إِلَى ٱللَّهِ ۖ قَالَ ٱلْحَوَارِيُّونَ نَحْنُ أَنصَارُ ٱللَّهِ ۖ فَـَٔامَنَت طَّآئِفَةٌۭ مِّنۢ بَنِىٓ إِسْرَٰٓءِيلَ وَكَفَرَت طَّآئِفَةٌۭ ۖ فَأَيَّدْنَا ٱلَّذِينَ ءَامَنُوا۟ عَلَىٰ عَدُوِّهِمْ فَأَصْبَحُوا۟ ظَٰهِرِينَ
Translation — Sahih International
O you who have believed, be supporters of Allah, as when Jesus, the son of Mary, said to the disciples, "Who are my supporters for Allah?" The disciples said, "We are supporters of Allah." And a faction of the Children of Israel believed and a faction disbelieved. So We supported those who believed against their enemy, and they became dominant.
