1739/1 - ‘Ā’ishah (may Allah be pleased with her) reported that the Prophet (may Allah’s peace and blessings be upon him) said: “None of you should say: My soul has become evil. But he should say: My soul is in bad shape.” [Narrated by Al-Bukhāri and Muslim]
Scholars said that both words have the same meaning, but the word “evil” is disliked.
1) It is advisable to avoid disliked words and to use Shariah-approved ones.
2) The Shariah encourages us to speak what is good in terms of words and meanings.
