What Doesn’t Break the Fast?
Things that do not invalidate the fast
- Eating or drinking by genuine forgetfulness (Sahih al-Bukhari 1933).
- Rinsing the mouth and nose in wudu, without exaggeration while fasting (Sunan Abu Dawud 142).
- Brushing the teeth or using a miswak, taking care not to swallow.
- Bathing, swimming and cooling the body.
- Tasting food on the tongue without swallowing, permitted by many scholars for a cook out of need.
- A wet dream, and being in a state of major impurity at dawn — ‘A’ishah and Umm Salamah reported the Prophet ﷺ would begin the fast in that state and then bathe (Sahih al-Bukhari 1926).
- Applying kohl, perfume, cream or eye drops, according to the majority.
- Unintentional vomiting.
Practical takeaway
Anything that is not eating, drinking, marital relations or their equivalents generally leaves the fast intact. Where a matter is genuinely disputed, ask a scholar rather than guessing in either direction.
