Surah 16. An-Nahl
Ayah 24 - 26
24 وَإِذَا قِيلَ لَهُم مَّاذَآ أَنزَلَ رَبُّكُمْ ۙ قَالُوٓا۟ أَسَـٰطِيرُ ٱلْأَوَّلِينَ
25 لِيَحْمِلُوٓا۟ أَوْزَارَهُمْ كَامِلَةً يَوْمَ ٱلْقِيَـٰمَةِ ۙ وَمِنْ أَوْزَارِ ٱلَّذِينَ يُضِلُّونَهُم بِغَيْرِ عِلْمٍ ۗ أَلَا سَآءَ مَا يَزِرُونَ
26 قَدْ مَكَرَ ٱلَّذِينَ مِن قَبْلِهِمْ فَأَتَى ٱللَّهُ بُنْيَـٰنَهُم مِّنَ ٱلْقَوَاعِدِ فَخَرَّ عَلَيْهِمُ ٱلسَّقْفُ مِن فَوْقِهِمْ وَأَتَىٰهُمُ ٱلْعَذَابُ مِنْ حَيْثُ لَا يَشْعُرُونَ
[24-26] And21 when they are asked, "What is it that your Lord has sent down?" they say these are mere fairy tales of the ancients.22 They say such things so that they should bear the full brunt of their own burdens on the Day of Resurrection together with some of the burdens of those whom they are leading astray in their ignorance. Behold! what a heavy responsibility they are taking on themselves! Many of those who have gone before them also contrived such cunning devices to defeat the Truth, but behold! Allah smote the edifice of their evil designs at its foundations and its roof fell down upon their heads from above them, and the scourge overtook them from the direction they little dreamed that it would come.
21In the preceding verse (23) those puffed up people, who were rejecting the Message were warned that Allah had full knowledge of all their "deeds." Now from v. 24 the Qur'an takes up those "deeds" one by one and deals with the arguments they presented against the Messenger, the objections they raised and the lame excuses they invented for their rejection, and reproaches and admonishes them.
22One of their cunning devices was to create doubts about the Qur'an. Whenever outsiders came to visit Makkah, they would naturally make inquiries about the Qur'an, which the Holy Prophet declared, was being sent down to him by Allah. The disbelievers would answer that it contained merely fairy-tales of the ancients. They would say such things in order to create doubts in the minds of the inquirers so that they should not take any interest in the Message of the Holy Prophet.
