(Al-Insan) 76 : 10
إِنَّا نَخَافُ مِنْ رَبِّنَا يَوْمًا عَبُوسًا قَمْطَرِيرًا

Indeed, we fear a gloomy dismal Day from our Lord.

The virtuous people lead a life here in a conscious that against the disbelievers who ignore Adhikr from this world, their skins, sights, hearings, etc. will witness on the Day of Judgement. Since the life way of Arabic Qur’an Reading Fujjar is against this, their mouths will be sealed on the Day of Judgement, their hands will speak what were their hands earning, and their legs will be witnessing against them as told in verse 36: 65; and on the Day the earth will  informs its news with the command of its Lord as told in verses 99: 4-5; and on that Day every secrets will be revealed as told in verse 86: 9.
On that Day the reckoning of every person will be done by reading himself the book of deeds fastened around his neck which will be given to him as an illuminated open book as told in verses 17: 13-14; 18: 49 23: 62-64; 36: 12; 45: 28-29; 8: 6 and 78: 29-30. The believer who understood these facts try to do the deeds, words and thoughts under the light of Adhikr so that he will get his book of deeds from the Hereafter in his right hand as explained in verses 69: 19-24. Such are the Muhsins who live here under the light of Adhikr-the Best. See explanation 39: 33; 58: 22 and 64: 16-17.
