The Ranks/61:14
"O you who believe, be supporters of Allah. Just as Jesus, son of Mary, asked his disciples, "Who will be my supporters in the way of Allah?"His disciples said, "We are the supporters of Allah."A group of the Children of Israel believed and a group disbelieved. We supported the believers against their enemies; they prevailed."
