۞ فَلَمَّآ أَحَسَّ عِيسَىٰ مِنْهُمُ ٱلْكُفْرَ قَالَ مَنْ أَنصَارِىٓ إِلَى ٱللَّهِ ۖ قَالَ ٱلْحَوَارِيُّونَ نَحْنُ أَنصَارُ ٱللَّهِ ءَامَنَّا بِٱللَّهِ وَٱشْهَدْ بِأَنَّا مُسْلِمُونَ
Translation — Sahih International
But when Jesus felt [persistence in] disbelief from them, he said, "Who are my supporters for [the cause of] Allah?" The disciples said, "We are supporters for Allah. We have believed in Allah and testify that we are Muslims [submitting to Him].
