that all that the believer commits in the world of bad deeds, he is requited for them with poverty, illness, humiliation, lowliness, hardship of living, misery, sadness, and difficulty of transition, until he does not exit from the world except that he has indeed been requited for all that he perpetrated in it of bad deeds and his good deeds purified in the Hereafter, so it is his prison from this aspect, and the meaning that it is his paradise is that in it he knows his Lord and purifies his sin and sees it with the eye of contempt, since he envisions his destiny to the abode of permanence, soothing his soul with the eternal bliss and the paradise which the pious were promised and the meeting of his Lord, satisfied and pleasing, and as for that it is the paradise of the disbeliever, then all that he works of good deeds in the world, he is requited for them with bliss, affluence, wealth, status, and health, up to other than that, until he does not exit from it except that he has indeed been requited for all the good deeds which he acquired in the phases of his life and escaped from them to the pure bad deeds so that he has deserved the transition from happiness to wretchedness.

And from al-Risalah al-Kawsariyyah of the late Sheikh 'Abd al-Hamid Mustafa,
