حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ، حَدَّثَنَا وَكِيعٌ، وَأَبِي، عَنِ الأَعْمَشِ، عَنْ شَقِيقٍ، عَنْ عَبْدِ اللَّهِ، قَالَ قُلْنَا ‏:‏ يَا رَسُولَ اللَّهِ أَنُؤَاخَذُ بِمَا كُنَّا نَفْعَلُ فِي الْجَاهِلِيَّةِ فَقَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ ‏:‏ ‏"‏ مَنْ أَحْسَنَ فِي الإِسْلاَمِ لَمْ يُؤَاخَذْ بِمَا كَانَ فِي الْجَاهِلِيَّةِ وَمَنْ أَسَاءَ أُخِذَ بِالأَوَّلِ وَالآخِرِ ‏"‏ ‏.‏

It wasnarrated from Abu Hurairah that the Messenger of Allah (ﷺ)said

“When the believer commits sin, a black spot appears on hisheart.If he repents and gives up that sin and seeks forgiveness, hisheartwill be polished. But if (the sin) increases, (the black spot)increases. That is the Ran that Allah mentions in His Book: “Nay!Buton their hearts is the Ran (covering of sins and evil deeds)whichthey used to earn.” [83:14]
