The Holy Quran, Chapter As-Saff - الصف

يَا أَيُّهَا الَّذِينَ آَمَنُوا كُونوا أَنصَارَ اللَّهِ كَمَا قَالَ عِيسَى ابْنُ مَرْيَمَ لِلْحَوَارِيِّينَ مَنْ أَنصَارِي إِلَى اللَّهِ قَالَ الْحَوَارِيُّونَ نَحْنُ أَنصَارُ اللَّهِ فَآَمَنَت طَّائِفَةٌ مِّن بَنِي إِسْرَائِيلَ وَكَفَرَت طَّائِفَةٌ فَأَيَّدْنَا الَّذِينَ آَمَنُوا عَلَى عَدُوِّهِمْ فَأَصْبَحُوا ظَاهِرِينَ

O ye who believe! Be Allah's helpers, even as Jesus son of Mary said unto the disciples: Who are my helpers for Allah? They said: We are Allah's helpers. And a party of the Children of Israel believed, while a party disbelieved. Then We strengthened those who believed against their foe, and they became the uppermost.
