If by mistake someone has sworn (taken out a bad word from one's mouth) and that is done very softly or silently or by mistake, does that break wudu?
In the Name of Allah, the Most Gracious, the Most Merciful.
Swearing does not break the wudu, even if it is done loudly. However, it is mustahab (praiseworthy/preferable) to renew one's wudu after committing a sinful act. (Noorul Idaah: pg 34)
And Allah knows best.
