١٨. قَدْ يَعْلَمُ ٱللَّهُ ٱلْمُعَوِّقِينَ مِنكُمْ وَٱلْقَآئِلِينَ لِإِخْوَٰنِهِمْ هَلُمَّ إِلَيْنَا ۖ وَلَا يَأْتُونَ ٱلْبَأْسَ إِلَّا قَلِيلًا
١٩. أَشِحَّةً عَلَيْكُمْ ۖ فَإِذَا جَآءَ ٱلْخَوْفُ رَأَيْتَهُمْ يَنظُرُونَ إِلَيْكَ تَدُورُ أَعْيُنُهُمْ كَٱلَّذِى يُغْشَىٰ عَلَيْهِ مِنَ ٱلْمَوْتِ ۖ فَإِذَا ذَهَبَ ٱلْخَوْفُ سَلَقُوكُم بِأَلْسِنَةٍ حِدَادٍ أَشِحَّةً عَلَى ٱلْخَيْرِ ۚ أُو۟لَـٰٓئِكَ لَمْ يُؤْمِنُوا۟ فَأَحْبَطَ ٱللَّهُ أَعْمَـٰلَهُمْ ۚ وَكَانَ ذَٰلِكَ عَلَى ٱللَّهِ يَسِيرًا
٢٠. يَحْسَبُونَ ٱلْأَحْزَابَ لَمْ يَذْهَبُوا۟ ۖ وَإِن يَأْتِ ٱلْأَحْزَابُ يَوَدُّوا۟ لَوْ أَنَّهُم بَادُونَ فِى ٱلْأَعْرَابِ يَسْـَٔلُونَ عَنْ أَنۢبَآئِكُمْ ۖ وَلَوْ كَانُوا۟ فِيكُم مَّا قَـٰتَلُوٓا۟ إِلَّا قَلِيلًا
[18-20] Allah knows very well those among you, who create hindrances (in the war efforts), who say to their brothers, "Come to us,"29 who take part in the fighting only to be counted in, who are ever reluctant to join you.30 When there is danger, they look towards you, their eyes rolling like the one who is fainting, being on the point of death. But when the danger is gone, they come out to greet you with their scissor-like sharp tongues in greed for gains.31 These people have not believed at all; so Allah has made all their works fruitless,32 and this is an easy thing for Allah.33 They think that the invading hosts are not yet gone, and if they should attack again they would (rather) wish to be in the desert among the Bedouins and seek information about you from there. However, even if they remained among you, they would take but little part in the fighting.
29That is, "Abandon this Prophet 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"Who are ever reluctant...: "Who are not at all willing to spend their energies, their time, their wealth, etc. in any way in which the true believers are expending 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. "
31Lexically, this verse has two meanings:
(1) "When you return victorious from a war, they receive you warmly, and try to impress you with a glib tongue that they too are sincere believers and they too have made their contribution to promote the cause of Islam, and therefore, they too 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 to the cause of Islam."
32That 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 co-operated 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-facedness, 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."
33That 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."
