If they turn away, then indeed Lord Allah is knowing with the mischief-makers.
All 313 Messengers were sent down with Adhikr to teach mankind that there is no deity except Lord Allah and to serve him alone as explained in verses 21: 24-25. In verse 7: 35 Lord says by calling mankind: “Whenever the Messengers come to you from among you explaining to you My verses, then those who are heedful and are reformers, there shall be no fear upon them and for them will not be grieved; and those who are rejecting Our verses and are arrogant about It, those are the inmates of Fire, they will remain in it forever”. The Fujjar who hide and reject Adhikr will witness against their soul that indeed they were disbelievers at the time of death vide verse 7: 37, and on the Day of Judgment vide verse 6: 130. The similitude of these hypocrites and their blind followers is that of a dog as told in verse 7:176, and that of a donkey as told in verse 62: 5.
It is told in verse 12: 3: “We explain upon you the best of the historical incidents by revealing this Reading into you, and before It you were among the heedless”. It is told in verse 12: 111: “Surely, there is a lesson in their history for those who are endowed with intelligence. This Speech is not being forged, but It is testifying what was before It and a detailed explanation of everything, and Guidance and Mercy for the believing people”. Verse 28: 77 ends as: “Indeed Lord Allah doesn’t like the mischief-makers”. Through verse 7: 103 believers are commanded to see the consequence of the mischief-makers. See explanation 2: 99 and 265-267.
