Wudu (ablution) is broken by specific things, and the list is shorter than many people fear. This guide covers what the texts and scholars say breaks wudu, then answers the everyday questions: burping, sneezing, crying, sweating, vomiting and bleeding. Where schools differ, it says so rather than giving one ruling for everyone.
The short answer
Most scholars agree on the core: anything that exits the front or back passage, and sleeping deeply, break wudu. Some further cases, such as flowing blood and vomiting, are disputed. Burping, sneezing, crying and sweating are not named among the nullifiers in the sources reviewed here. Always follow your own school or a local scholar for anything borderline.
Why wudu matters and when it breaks
Allah commands wudu for prayer: when you rise to pray, wash your face and hands to the elbows, wipe your heads and wash your feet to the ankles (Surah Al-Ma'idah, 5:6). The same verse mentions relieving yourself as a cause for needing purification again.
The Prophet ï·º said that the prayer of one of you is not accepted if he has broken wudu until he performs ablution (Sahih Muslim 225). When Abu Hurairah was asked what hadath (breaking wudu) means, he explained it as passing wind (Sahih al-Bukhari 176).
Things that clearly break wudu
- Passing wind, urine or stool. Darul Ifta Birmingham, a Hanafi-based institution, states that anything exiting the front or back passage nullifies wudu, and that passing even a small amount of gas counts once you are certain of it (Passing Wind).
- Prostatic or pre-seminal fluid (madhy). Ali ibn Abi Talib asked about this fluid and the Prophet ï·º replied that wudu is required for it (Sahih al-Bukhari 178).
- Deep sleep. A narration reports the Prophet ï·º saying that whoever sleeps should perform wudu (Sunan Abi Dawud 203), while another reports Companions dozing while waiting for the night prayer and then praying without fresh wudu (Sunan Abi Dawud 200). Scholars reconcile these by the depth of sleep. See does sleeping break wudu for the detail.
Doubt does not break wudu
When someone imagined they had broken wind during prayer, the Prophet ï·º said not to leave the prayer unless you hear a sound or smell something (Sahih al-Bukhari 177). Darul Ifta Birmingham applies this: wudu does not break until you are sure that gas has exited the body, even if you feel gas moving or bubbles at the surface (Gas Bubbles Breaking Wudu). If you struggle with constant doubt, treat your wudu as intact unless you are certain.
Burping, sneezing, crying and sweating
None of the sources reviewed for this guide lists burping, sneezing, crying or sweating as breaking wudu. Be careful about what that does and does not show:
- Burping and sneezing: A Birmingham fatwa says yawning, sneezing, coughing or belching does not invalidate salah as long as it is natural (Making Sounds in Salah). That answer is about the prayer itself, not about wudu, and it is a Hanafi-based ruling.
- Crying and sweating: These are not exits from the passages that the texts above associate with hadath, so nothing in the sources reviewed treats them as nullifiers. Ask a scholar if you have a specific concern.
Where scholars differ: vomiting and blood
Vomiting. Egypt's Dar al-Ifta states that vomiting does not nullify ablution, though it is impure and the mouth and any soiled area must be cleaned before prayer (Vomiting and ablution). Others rely on a narration in which the Prophet ï·º vomited and then performed wudu (Jami at-Tirmidhi 87). Because this is disputed, following your school is the safe course. Performing fresh wudu is always permissible.
Blood. According to Darul Ifta Birmingham, Imam Abu Hanifa held that flowing blood breaks wudu, while Imam Shafi'i and Imam Malik held that wudu remains intact (Hanafi proofs for blood breaking wudu). Our guide to does bleeding break wudu compares the schools in full.
What to do next
- If your wudu may have broken and you are sure, make wudu again; the steps are in how to perform wudu.
- If you are only in doubt, keep your wudu and carry on.
- For disputed cases, follow your school or ask a qualified local scholar.
- Check your next prayer time with the prayer times tool so you can plan wudu before it starts.

Frequently asked questions
Does burping break wudu?
The sources reviewed do not list burping as a nullifier of wudu. A Hanafi-based Birmingham fatwa says natural belching does not invalidate salah, though that answer concerns prayer. Follow your school if unsure.
Does sneezing or crying break wudu?
Neither is named among the nullifiers in the texts and fatwas reviewed. Sneezing is treated by a Birmingham fatwa as not invalidating salah when natural. Ask a scholar about specific circumstances.
Does sweat break wudu?
Sweat is not an exit from the front or back passage and is not named as a nullifier in the sources reviewed. Scholars name specific causes, and sweating is not among them in these sources.
Does vomiting break wudu?
Scholars differ. Egypt's Dar al-Ifta says vomiting does not nullify wudu but is impure, while a narration in Tirmidhi reports the Prophet vomiting and performing wudu. Follow your school, and making wudu again is always allowed.
What if I am not sure whether I broke wind?
Your wudu stays intact. The Prophet said not to leave prayer unless you hear a sound or smell something, and Darul Ifta Birmingham says wudu does not break until you are certain.
