Great little summary here:
The Qurʾān mentions only two events involving the apostles of Jesus. In q 5:112 the apostles ask Jesus to have God send down a table of food to satisfy their hunger and strengthen their faith. Jesus agrees to do so, but warns them that, because they have witnessed such a confirmation of faith, God will tolerate no future deviation from faith on their part. The second instance takes place at the end of Jesus' mission. When he is under attack from unbelievers, his apostles testify to the constancy of their faith in him. Jesus asks, “Who will be my helpers to God?” His apostles answer, “We are God's helpers! We believe in God and do you bear witness that we are Muslims. Our lord! We believe in what you have revealed and we follow the messenger. Then write us down among those who bear witness ( q 3:52-3).” One final passage probably refers to the apostles of Jesus and his other followers: “We sent… Jesus the son of Mary (q.v.), and bestowed on him the Gospel (q.v.); and We ordained in the hearts of those who followed him compassion and mercy” ( q 57:27).
