18. In( Ayats 9-27), an appraisal has been made of the battle of the Trench and the raid against the Bani Quraizah. These were revealed at the end of the raid. One should keep the details of these events in view as given in the introduction above.
19. The windstorm did not lash the enemy forces immediately on their arrival but it occurred while the siege of Al-Madinah had lasted about a month. “Armies whom you did not see” implies the hidden powers which operate in the affairs of men under Allah’s command and of which men are totally unaware. Man regards the occurrence of events and incidents as resulting from apparent causes and does not take into account the hidden forces at work, whereas in most cases these very hidden forces play the decisive role. As these forces function under the command of Allah’s angels, the “armies” may imply the angels as well though there is no indication here of sending the armies of the angels.
20. It may mean: The enemies came upon you from every side, and also that those coming from Najd and Khaiber came from above and those coming from Makkah from below you.”
21. “The believers”: All those who accepted the Prophet (peace be upon him) as Allah’s Messenger and became included among his followers, which comprised both the true believers and the hypocrites. In this paragraph Allah has made mention of the Muslim community as a whole. In the following three paragraphs the attitude of the hypocrites has been commented upon, and the next two deal with the Prophet (peace be upon him) and the true believers.
22. That is, “Promises to the effect that the believers will get Allah’s support and succor and will be helped to attain victory in the end.”
23. This sentence has two meanings: The apparent meaning is that there is no chance for them to stay at the Trench against the polytheists; therefore, they should return to the city. And the hidden meaning is that there is no chance for them to remain in Islam; therefore, they should return to their ancestral religion, so that they might escape the danger in which they had involved themselves by earning the hostility of the whole of Arabia. The hypocrites uttered such mischievous things so that they could make the one who would listen to them understand the intended hidden meaning, but in case someone took exception to their words, they could say they had been misunderstood.
24. That is, when the Bani Quraizah also joined the invaders, the hypocrites had a good excuse for defection and they started asking the Prophet (peace be upon him) for leave to go and protect their houses and families, which, they said, had been endangered, whereas at that time the Prophet (peace be upon him) was responsible for the defense and protection of all the people of Al-Madinah. After the treachery of the Quraizah it was for the Prophet (peace be upon him) to devise plans for the protection of the city and its people and not of the soldiers of the army individually.
25. That is, the Prophet (peace be upon him) had already made arrangements for protection against the danger, which were a part of the collective scheme of defense being implemented by him as commander of the Islamic forces. Therefore, there was no immediate danger in the face of which these people could justifiably make such an excuse.
26. “Exhorted to treachery”: Urged by the disbelievers to join them to vanquish the Muslims after entering the city as conquerors.
27. That is, they had felt regret at the weakness they had shown on the occasion of the battle of Uhud and pledged to Allah that they would compensate for their error in any trial that they would confront in the future. But Allah cannot be deceived by empty words. He puts to one or the other test everyone who makes a pledge with Him so that his sincerity of intention or otherwise is found out. Therefore, just after two years of the battle of Uhud, He made them confront an even more serious danger and discovered how far they were sincere in their pledge.
28. That is, this flight of yours will not add anything to your life. In no case will you live forever and gain the whole wealth of the world. Hardly a few years will you live after your flight and enjoy life only as long as it is destined for you.
29. That is, abandon this Prophet (peace be upon him) and do not become involved in dangers and afflictions only for the sake of the faith and truth. Live a life of ease and comfort as we do.
30. “Being miserly”: Those who are not at all willing to spend their energies, their time, their wealth, etc. in any way in which the true believers are spending whatever they have. Not to speak of exerting themselves and braving the dangers, they do not want to cooperate with the believers in anything with an open heart.
31. Lexically, this verse has two meanings:
(1) When you return victorious from a war, they receive you warmly, and try to impress you with a sweet tongue that they too are sincere believers and they too have made their contribution to promote the cause of Islam, and therefore, they deserve a share from the booty.
(2) If victory is attained, these people show great powers of the tongue at the time of the division of the spoils and make great demands for their shares, recounting their services for the cause of Islam.
32. That is, Allah will make null and void all the prayers that they offered, all the fasts that they observed, the zakat that they paid, and other good works that they did after embracing Islam, and will give them no reward for these. For Allah does not judge actions and deeds according to their external form but on the basis of the faith and sincerity underlying them. When the actions are altogether devoid of this quality, there will be mere show and, therefore, meaningless. Here, one thing is especially noteworthy. A clear verdict has been given about the people who professed to believe in Allah and His Messenger, offered the Prayers, observed the fast, gave the Zakat and cooperated with the Muslims in other good works, to the effect that they did not believe at all. This verdict has been given because when they were put to the test during the conflict between Islam and un-Islam, they showed double standard, preferred selfish interests above the interests of the faith, and shirked offering their selves and their wealth and their energies for the protection of Islam. This shows that the real criterion of the judgment are not the apparent deeds but the loyalties of man. If a person is not loyal to God and His way, his profession of the faith and his worship and other good deeds are worthless.
33. That is, as their deeds and actions do not carry any value, Allah renders them fruitless without the slightest hesitation; and as they do not have any power to resist. Allah has no difficulty in destroying their deeds altogether.
