Ali 'Imran 3:52

Falamma ahassa AAeesaminhumu alkufra qala man ansaree ila Allahiqala alhawariyyoona nahnu ansaruAllahi amanna billahi washhadbi-anna muslimoon

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].

So, when ‘Īsā sensed disbelief in them, he said: “Who are my helpers in the way of Allah?” The disciples said: “We are helpers of Allah. We believe in Allah; so be our witness that we are Muslims.”
