Surely, those who rejected the meeting with Lord Allah are lost, until when the Hour comes suddenly to them, they will wail: "Our loss! We were thoughtless about it". And they will be carrying their burden upon their backs; know! What an evil burden they are bearing.
The Hour mentioned in verse is the death time for individuals and the Doomsday for the whole of mankind. It is told in verses 10: 7-8 that indeed those who are not expecting the meeting with their Lord, satisfied and tranquil with the worldly life, and heedless about Lord's verses will have Hellfire as an abode since they were earning it. If the disbelievers are warned about the meeting with their Lord with Adhikr, they will ask to bring a book other than this or to make some changes in It as explained in verse 10: 15. It is told in verse 10: 45 that those who deny the meeting with their Lord and reject His verses are the losers. It is told in verse 29: 23: that those who hide the verses of the Lord and the meeting with Him have despaired of Lod's Mercy, and they will have a painful punishment.
It is told in verses 84: 6: "Oh mankind, indeed you are laboring toward your Lord with great effort and will meet Him". It is told in verses 39: 54-55: "And you return in repentance to your Lord and submit wholly to Him before the punishment comes upon you; then you will not be helped. And you follow the Best Book Adhikr revealed upon you from your Lord before the punishment comes upon you suddenly while you don't perceive".
The Arabic Quran reading Fujjar are reading these verses among mankind. Since they are hiding and rejecting Adhikr, at the time of anyone of their death Lord will say: "Nay you have received my verses, but you rejected them and were arrogant. Indeed, you were among the disbelievers" as told in verse 39: 59. The burden carrying upon the backs of Fujjar are the evil deeds that they had done in this world and that is being recorded in their Recording Book fastened upon their necks as explained in verses 17: 13-14. It is told in verses 20: 99-100 that whoever neglects the Book Dhikra, should bear a burden on the Day of Judgment. The worst creatures Fujjar explained in verse 8: 22 will have to bear the burden of all difficulties and distresses suffered by the thousand communities of Lord's creatures since they hide and reject Adhikr which is the Balance and Trust to keep the universe in its equilibrium. See explanation 2: 121, 186; 4: 85, and 6: 4.
