Translation:

14. O ye who believe! be ye helpers of Allah: as said Jesus the son of Mary to the Disciples "Who will be my helpers to (the work of) Allah?" Said the Disciples "We are Allah's helpers!" Then a portion of the Children of Israel believed and a portion disbelieved: but We gave power to those who believed against their enemies and they became the ones that prevailed.

Notes (Tafseer)

5446. If we seek Allah's help, we must first help Allah's Cause, i.e., dedicate ourselves to Him entirely and without reserve. This was also the teaching of Jesus, as mentioned in this verse.

5447. See iii. 52, and n. 392; and for the Biblical reference, see the last note. The names of the twelve Disciples will be found in Matt. x. 2-4.

5448. A portion of the Children of Israel-the one that really cared for Truth-believed in Jesus and followed his guidance. But the greater portion of them were hard hearted, and remained in their beaten track of formalism and false racial pride. The majority seemed at first to have the upper hand when they thought they had crucified Jesus and killed his Message. But they were soon brought to their senses. Jerusalem was destroyed by Titus in A.D. 70 and the Jews have been scattered ever since. "The Wandering Jew" has become a bye-word in many literatures. On the other hand, those who followed Jesus permeated the Roman Empire, brought many new races within their circle, and through the Roman Empire, Christianity became the predominant religion of the world until the advent of Islam. So is it promised to the people of Islam: they must prevail if they adhere to the Truth. Badr (A.H. 2) was a landmark against Pagan Arabia; Qadisiya (A.H. 14) and Madain (A.H. 16) against the might of Persia: Yarmuk (A.H. 15) against the might of the Byzantine Empire in Christian Syria; and Heliopolis (A.H. 19) against the same Empire in Christian Egypt and Africa. These were symbols in external events. The moral and spiritual landmarks are less tangible, and more gradual, but none the less real. Mark how the arrogance and power of Priesthood have been quelled; how superstition and a belief in blind Fate have been checked; how the freedom of human individuals has been reconciled with the sanctity of marriage in the law of Divorce; how the civil position of women has been raised; how temperance and sobriety have been identified with religion; what impetus has been given to knowledge and experimental science; and how economic reconstruction has been pioneered by rational schemes for the expenditure and distribution of wealth.
