The Book of the Prohibited actions

Riyad as-Salihin · Chapter 329

Abomination of Self-Condemnation

باب كراهة قوله‏:‏ خبثت نفسي

This short chapter is about the weight our words carry, even the offhand ones we mutter about ourselves. The Prophet (peace be upon him) corrected a particular habit of speech: calling one's own soul khabithat, a word tied to filth and corruption. The teaching is gentle but precise. We are allowed to admit we feel low or out of sorts, but not to brand the soul Allah entrusted to us with the language of evil.

Notice how the Prophet (peace be upon him) does not forbid honesty about a bad mood; he offers a cleaner way to say the same thing. The Buruja takeaway is the care a believer gives to the tongue, choosing words that describe a passing state without insulting the gift of one's own self.

Hadith 1739

'Aishah (May Allah be pleased with her) said:

عن عائشة رضي الله عنها عن النبي صلى الله عليه وسلم قال‏:‏ ‏ "‏لا يقولن أحدكم خبثت نفسي، ولكن ليقل‏:‏ لقست نفسي‏" ‏ ‏(‏‏(‏متفق عليه‏)‏‏)‏‏.‏ قال العلماء معنى خبثت أي غثيت وهو معنى لقست ولكن كره لفظ الخبث

The Prophet (ﷺ) said, "None of you should say: 'My soul has become evil.' He should say: 'My soul is in bad shape."' [Al-Bukhari and Muslim].

In plain words

One should not say 'my soul has become evil,' but rather 'my soul is in bad shape.' Admitting a low mood is fine; branding the soul with the language of evil is not.
