❖ Question:
What is the ruling regarding a person who habitually swears oaths in regular speech?
❖ Answer:
If a person uses oaths as a habitual phrase in their speech, then such oaths hold no legal weight. These are considered vain (laghw) oaths, and no expiation (kaffārah) is required for them.
❀ Allah Almighty states:
﴿لَا يُؤَاخِذُكُمُ اللَّهُ بِاللَّغْوِ فِي أَيْمَانِكُمْ﴾
(Surah al-Baqarah: 225)
“Allah will not call you to account for your unintentional (vain) oaths.”
❀ Sayyidah ʿĀ’ishah رضي الله عنها said regarding this verse:
“This verse was revealed about the people’s habit of saying in their speech: ‘By Allah! By Allah!’”
(Ṣaḥīḥ al-Bukhārī: 6663)
Meaning, unintentional oaths uttered casually or as a habitual phrase during conversation are regarded as Yamīn Laghw (vain oaths).
✅ Conclusion:
◈ Oaths uttered out of habit in ordinary speech carry no legal consequence.
◈ They are classified as vain oaths (لغو قسم).
◈ No expiation (kaffārah) is necessary in such cases.
