وَحَدَّثَنِي أَبُو الطَّاهِرِ، وَحَرْمَلَةُ، قَالاَ أَخْبَرَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي يُونُسُ، عَنِ ابْنِ، شِهَابٍ عَنْ أَبِي أُمَامَةَ بْنِ سَهْلِ بْنِ حُنَيْفٍ، عَنْ أَبِيهِ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ لاَ يَقُلْ أَحَدُكُمْ خَبُثَتْ نَفْسِي ‏.‏ وَلْيَقُلْ لَقِسَتْ نَفْسِي ‏"‏ ‏.‏

Abu Umama b. Sahl b. Hunaif, on the authority of his father, reported Allah's Messenger (ﷺ) as saying: None of you should say:" My soul has become evil," but he should say:" My soul has become remorseless."
