O you who believe! be helpers of (the cause of) Allâh (as did the disciples of Jesus), for when Jesus, son of Mary, said to the disciples, `Who will join me as my helper towards (the cause of) Allâh?' The disciples replied, `We are helpers of (the cause of) Allâh.' So a section of the Children of the Israel believed (firmly in Jesus), while another section rejected (him). Thereupon We helped those who believed, against their enemies and (at last) these (believers) gained predominant victory (over the nonbelievers).
