None of you should say: "My soul has become evil," but he should say: "My soul has become remorseless." This hadith has been transmitted on the authority of Abu Bakr with a slight variation of wording.  

قَالَ رَسُولُ اللَّهِ ﷺ لاَ يَقُولَنَّ أَحَدُكُمْ خَبُثَتْ نَفْسِي وَلَكِنْ لِيَقُلْ لَقِسَتْ نَفْسِي هَذَا حَدِيثُ أَبِي كُرَيْبٍ وَقَالَ أَبُو بَكْرٍ عَنِ النَّبِيِّ ﷺ وَلَمْ يَذْكُرْ لَكِنْ  

This hadith has been narrated on the authority of Abia Mu'iwiya with the same chain of transmitters.  

حَدَّثَنَا أَبُو مُعَاوِيَةَ بِهَذَا الإِسْنَادِ  

None of you should say:" My soul has become evil," but he should say:" My soul has become remorseless."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ يَقُلْ أَحَدُكُمْ خَبُثَتْ نَفْسِي وَلْيَقُلْ لَقِسَتْ نَفْسِي
