Falamma ahassa AAeesa minhumu alkufra qala man ansaree ila Allahi qala alhawariyyoona (surah Al Imran: 52)

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(3:52) And when Jesus perceived their leaning towards unbelief, he asked: 'Who will be my helpers in the way of Allah?' The disciples *49 said: 'We are the helpers of Allah. We believe in Allah, *50 and be our witness that we have submitted ourselves exclusively to Allah.

Falammaaa ahassa `Eesaa minhumul kufra qaala man ansaaree ilal laahi qaalal Hawaariyyoona nahnu ansaarul laahi aamannaa billaahi washhad bi annaa muslimoon

*49). The word hawari means approximately the same as the word ansar in the Islamic tradition. In the Bible the usual terms are 'apostles' and 'disciples'. Jesus' chosen disciples were called apostles in the sense that they had been entrusted with a mission by him rather than in the sense of having been entrusted with a mission by God.
*50). At various places the Qur'an characterizes man's participation in the effort to establish the supremacy of Islam as 'helping God'. This needs a little explanation. God has endowed man with the freedom of will and choice, with the result that He does not resort to His omnipotent will to compel man either to do certain things or to refrain from others. He rather leaves man free to adopt the course that pleases him - be it that of either belief or unbelief, of either obedience or disobedience. God prefers to instruct man by means of persuasive argument and admonition, so as to bring home to him that even though he is free to disbelieve, disobey and defy the Will of God, his own interest and well-being lie in serving and obeying his Creator.
Hence, directing people to the right path by persuasion and admonition is of concern to God, He regards those who contribute to this cause as His allies and helpers. This is, in fact, the most exalted position attainable by man. When a man performs Prayers, keeps his fast and worships God in other ways, he is merely on the level of service and subjection to God. But when a man strives to spread God's true religion and to enthrone it in actual life, he is honoured with the status of God's ally and helper, which is the zenith of man's spiritual growth.
