Does Nail Cutting Affect Wudu in Islam?

Someone asked: “I cut my nails after making wudu (ablution), shall I renew my ablution or washing my hands will be enough?”

No, cutting your nails does not break your wudu, whether done before or after ablution. It does not affect the validity of your wudu.

You aren’t obliged to renew your wudu (ablution) nor to wash your hands according to your case whether cutting nails was done before or after making wudu. The same ruling applies to trimming the hair, since they won’t invalidate wudu. However, if you want to wash your hands for personal hygiene, then it’s up to you.
