Qur'an 3:52
۞ فَلَمَّآ أَحَسَّ عِيسَىٰ مِنْهُمُ ٱلْكُفْرَ قَالَ مَنْ أَنصَارِىٓ إِلَى ٱللَّهِ ۖ قَالَ ٱلْحَوَارِيُّونَ نَحْنُ أَنصَارُ ٱللَّهِ ءَامَنَّا بِٱللَّهِ وَٱشْهَدْ بِأَنَّا مُسْلِمُونَ
“But when Jesus felt [persistence in] disbelief from them, he said, "Who are my supporters for [the cause of] Allāh?" The disciples said, "We are supporters for Allāh. We have believed in Allāh and testify that we are Muslims [submitting to Him].”
