Aal-'Imran - 3:52

فَلَمَّا أَحَسَّ عِيسَى مِنْهُمُ الْكُفْرَ قَالَ مَنْ أَنصَارِي إِلَى اللّهِ قَالَ الْحَوَارِيُّونَ نَحْنُ أَنصَارُ اللّهِ آمَنَّا بِاللّهِ وَاشْهَدْ بِأَنَّا مُسْلِمُونَ
[3:52]
But when Isa perceived unbelief on their part, he said Who will be my helpers in Allah's way? The disciples said: We are helpers (in the way) of Allah: We believe in Allah and bear witness that we are submitting ones.
When Jesus found Unbelief on their part He said: "Who will be My helpers to (the work of) Allah?" Said the disciples: "We are Allah's helpers: We believe in Allah, and do thou bear witness that we are Muslims.
But when Jesus became conscious of their disbelief, he cried: Who will be my helpers in the cause of Allah? The disciples said: We will be Allah's helpers. We believe in Allah, and bear thou witness that we have surrendered (unto Him).
