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."
Why did Jesus, son of Mary, ask for followers?
The Family Of Imran/3:49
"As a messenger sent to the Children of Israel (he will say): ´I have come to you with a proof from your Lord. I will make you a statue of a bird out of clay and blow into it, and by Allah´s permission it will become a bird. By Allah´s permission I will cure the blind and the leper and raise the dead. I can let you know what you eat and what you store in your houses. These proofs are sufficient for you if you believe."
The Family Of Imran/3:50
"´I have been sent to confirm the Torah that was before me and to make lawful for you some things that were forbidden to you. I bring you a proof from your Lord, so listen to Allah and follow me.
The Family Of Imran/3:51
"Allah is my Lord and your Lord; serve Him. This is the right way."
The Family Of Imran/3:52
"When Jesus sensed a disbelieving attitude from them, he said, "Who will help me in the way of Allah?"His disciples said, "We are God´s helpers; we have believed in God. Witness that we have become Muslims."
The Family Of Imran/3:53
Our Lord, we believe in what You have sent down and we have followed the messenger; put us on the list of witnesses!
