This surah seeks to establish two major themes which permeate its entire text. It also includes a number of secondary references which relate to those major themes.

The first aim of the surah is to establish in the conscience of every Muslim the fact that his religion is the final version of the divine system God has laid down for mankind. There were earlier versions, each suited for a particular period of human history. There were also experiences in the lives of earlier messengers and past communities that afforded much to reflect upon. All these have paved the way for this final version of the one divine faith. It incorporates Gods final message for mankind, which He has willed to prevail over all other religions.

Hence, the surah mentions Moses’ message, making it clear that his people caused him much grief and deviated from his message. They had gone astray and were no longer to be trustees of the divine faith: “Now when Moses spoke to his people, he said: ‘My people! Why do you cause me grief, when you know that I am a messenger God has sent to you? So, when they swerved from the right way, God let their hearts swerve from the truth.

God does not bestow His guidance upon evildoers.” (Verse 5)

The surah then mentions Jesus’ message to establish that Jesus was sent to carry on Moses’ earlier message, confirming what was revealed before him of the Torah. He was also given the task of paving the way for the final message, giving news of the Messenger who was to carry it, and serving as a link between the first and the last divine religions. “And also Jesus, the son of Mary, said: Children of Israel! I am God's messenger to you, [sent] to confirm the Torah revealed before me, and to give news of a messenger that will come after me, whose name shall be Ahmad " (Verse 6) Hence, his task was to carry the trust of the divine faith after Moses and then to give it to the Messenger whose coming he announced.

It was always confirmed, according to God’s knowledge and by His will, that these steps would eventually lead to a final and permanent version to establish God’s faith in human life, and this by the final Messenger: “Zr is He who has sent His Messenger with guidance and the religion of truth, so that He may cause it to prevail over all other religions, however hateful this may be to the idolaters." (Verse 9)

This first clear purpose of the surah gives rise to its second purpose.

When a Muslim is fully aware of this fact, knows the history of the divine faith and is aware of his share of it, he realizes the duties that this trust involves. Hence, he has a clear and sincere motive for striving to ensure that this faith prevails over all other religions, just as God wants it to do. There is no longer any vacillation in practically carrying out what one verbally has proposed to do. It is inappropriate for a believer to declare his intention to strive for God’s cause but then to refrain from doing so. According to some reports, it appears that there were some cases of this sort. Hence, the surah starts with a proclamation that the entire universe and all that is in it unceasingly glorify God.

“Believers! Why do you say what you do not do? Most loathsome is it in the sight of God that you say what you do not do! God loves indeed those who fight in His cause in solid ranks, as though they were a firm and compact building" (Verses 2—4)

In the middle of the surah, the believers are called upon to take part in the most profitable transaction that they could have in this life and in the life to come: “ Believers! Shall i point out to you a bargain that will save you from grievous suffering? You are to believe in God and His Messenger, and to strive hard in God's cause with your possessions and your lives. This is for your own good, if you but knew it. He will forgive you your sins, and [in the life to come] will admit you into gardens through which running waters flow, and into goodly mansions in the gardens of Eden. That is the supreme triumph! And [He will grant you]yet another thing that you dearly love: help from God and a victory soon to come. Give you the good news to the believers.” (Verses 10-13)

The surah ends with an appeal to the believers to be the helpers in furthering Gods cause, just like Jesus’ disciples who supported him when the Israelites continued to deny his message and were hostile towards him: “Believers! Be helpers [in the cause] of God; just as Jesus, the son of Mary, said to the disciples: “Who will be my helpers in God's cause?" The disciples said: “We shall be [your] helpers in God's cause. "And so some of the Children of Israel came to believe whereas others denied the truth. But We have given those who believed strength over their enemy and they were the ones to prevail." (Verse 14)

These two purposes are very clear throughout the surah, taking up nearly all of its text. There only remains a denunciation of those who reject the final message, which is clearly linked to the two main themes. We see this clearly stated after Jesus gave the news of the impending appearance of the final Messenger, the Prophet Muhammad (peace be upon him):

“But when he came to them with all evidence of the truth, they said: 'This is plain sorcery.' Who could be more wicked than one who invents a falsehood about God, when he is only being called upon to submit to Him? God does not bestow His guidance upon the wrongdoers. They aim to extinguish God's light with their mouths, but God will spread His light in all its fullness, however hateful this may be to the unbelievers."(Verses 6-8)

Thus, every Muslim is clear in his mind that his faith is the final version of the religion God wants to be established on earth. He realizes that the trust of this divine faith is given to him, and he knows that he is required to strive for God’s cause as God wants. His line is clear, leaving no room for ambiguity, hesitation or faltering. The goal is well defined and the way to achieve it is made clear.

With this goal-defining directive we also have clear pointers to the nature of the moral code a Muslim must follow. A Muslim must demonstrate consistency between his conscience and his action. He cannot say one thing and then do another. His appearance must not fundamentally differ from what he conceals within himself. He must be consistent in all situations, dedicated in his service to Gods cause, clear in both his intention and action, moving with steady steps, collaborating with his brothers so that the Muslim community is seen to be solid and firm like a building with strong foundations.
