Surat Yunus (15-16)

{وَإِذَا تُتْلَى عَلَيْهِمْ آيَاتُنَا بَيِّنَاتٍ قَالَ الَّذِينَ لاَ يَرْجُونَ لِقَاءنَا ائْتِ بِقُرْآنٍ غَيْرِ هَـذَا أَوْ بَدِّلْهُ قُلْ مَا يَكُونُ لِي أَنْ أُبَدِّلَهُ مِن تِلْقَاء نَفْسِي إِنْ أَتَّبِعُ إِلاَّ مَا يُوحَى إِلَيَّ إِنِّي أَخَافُ إِنْ عَصَيْتُ رَبِّي عَذَابَ يَوْمٍ عَظِيمٍ} (يونس : 15)

15- When the clear Ayahs of the Glorious Qur'an that indicate monotheism are recited to polytheists, the people who do not believe in the Day of Recompense and do not fear the reckoning say: Bring another book other than the Qur'an that does not contain dispraise to our gods, the mention of the Day of Resurrection or replace the Ayahs that contain these matters with another.

O Prophet, tell them: This is not my business and I cannot change it because I am only a commanded servant and a messenger who delivers the words of Allah. I do not follow but the ordinances of Allah that are revealed to me regarding things which He commands and prohibits without change or replacement. I fear if I change the words of Allah or disobey His Commands that He would torture me severely on the Day of Recompense.

Ibn Al Jawzy said in An-Nawasikh: This Ayah and the like explain the effect of sins, and it is not necessary if something is connected with a cause to fall.

{قُل لَّوْ شَاء اللّهُ مَا تَلَوْتُهُ عَلَيْكُمْ وَلاَ أَدْرَاكُم بِهِ فَقَدْ لَبِثْتُ فِيكُمْ عُمُراً مِّن قَبْلِهِ أَفَلاَ تَعْقِلُونَ} (يونس : 16)

16- Say to them: If Allah had willed, He would not have revealed the Qur'an to me or rected it to you. I stayed among you for 40 years before it had been revealed to me and you had not tried laying from me. Do not you ponder over and know that the Qur'an is not made by me? I did not ask a scholar, read a book, or write a word, but this eloquent book which contains rulings, history, stories, and unseen matters was truly revealed from Allah.
