Surah 25. Al-Furqan
Ayah 18 - 19
18قَالُوا۟ سُبْحَـٰنَكَ مَا كَانَ يَنۢبَغِى لَنَآ أَن نَّتَّخِذَ مِن دُونِكَ مِنْ أَوْلِيَآءَ وَلَـٰكِن مَّتَّعْتَهُمْ وَءَابَآءَهُمْ حَتَّىٰ نَسُوا۟ ٱلذِّكْرَ وَكَانُوا۟ قَوْمًۢا بُورًا
19فَقَدْ كَذَّبُوكُم بِمَا تَقُولُونَ فَمَا تَسْتَطِيعُونَ صَرْفًا وَلَا نَصْرًا ۚ وَمَن يَظْلِم مِّنكُمْ نُذِقْهُ عَذَابًا كَبِيرًا
[18-19] They will answer, "Glory be to Thee! We dared not take any guardian besides Thee: (they were misled because) Thou didst give them and their forefathers all the good things of life till they forgot the Admonition, and incurred the punishment."26 Thus will your gods deny all that you are professing today.27 Then you shall neither be able to repel your punishment nor shall get any help from anywhere; and whoso is guilty. of iniquity''28 among you, We shall make him taste a severe torment.
26That is, "They were mean people: You gave them all the provisions of life so that they may show gratitude to You, but they became ungrateful and ignored all the admonitions given by the Prophets. "
27That is, "On that Day your religion, which you now believe, to be true. will prove to be false and even your gods, whom you yourselves have set up,' will declare it to be a lie; for none of them ever asked you to make them your deities and worship them as such. Consequently, instead of interceding on your behalf; they will bear witness against you."
28"... who will be guilty of iniquity ...": " .... who will be unjust to the Reality and the Truth and guilty of disbelief and shirk "The context shows that those who reject the Prophet and set up other deities instead of Allah and deny life in the Hereafter, are guilty of zulm (iniquity).
