What Breaks Wudu? The Complete Authentic List

Wudu is the key to prayer. Allah says:

“O you who believe, when you rise for prayer, wash your faces and your hands up to the elbows, and wipe your heads, and (wash) your feet up to the ankles.” (Quran 5:6)

But what exactly ends the state of wudu? Below is the complete list of nullifiers, according to the Hanafi school, with the evidence for each — followed by the things people commonly think break wudu but do not.

The Things That Break Wudu

1. Anything that exits from the front or back passage

Urine, stool, wind, madhi (pre-seminal fluid) and wadi all break wudu by consensus. Regarding madhi, the Prophet ﷺ instructed that the private part be washed and wudu performed. (Sahih al-Bukhari 269 · Sahih Muslim 303)

2. Blood or pus that flows

If blood or pus comes out of a wound and flows beyond the point of exit, wudu breaks. If it stays at the surface without flowing, it does not. This flowing condition is the established position of the Hanafi school, drawn from the practice and reports of the Companions.

3. Vomiting a mouthful

The Prophet ﷺ vomited and then performed wudu. (Sunan Abu Dawud 2381 · Jami’ at-Tirmidhi 87) In the Hanafi school, a mouthful of vomit breaks wudu; a small amount that does not fill the mouth does not.

4. Sleeping lying down, or leaning on something

Sleep in which the muscles fully relax — lying down, or leaning such that if the support were removed one would fall — breaks wudu. The Prophet ﷺ said: “The eye is the drawstring of the anus; whoever sleeps should perform wudu.” (Sunan Abu Dawud 203 · Sunan Ibn Majah 477 — Hasan)

However, a light doze while sitting firmly does not break wudu: the Companions would doze while waiting for the Isha prayer and then pray without renewing wudu. (Sahih Muslim 376 · Sahih al-Bukhari 212)

5. Losing consciousness or sanity

Fainting, intoxication or insanity — even briefly — breaks wudu, because awareness is lost more completely than in sleep.

6. Laughing aloud (qahqaha) during prayer

Audible laughter during salah breaks both the prayer and the wudu in the Hanafi school, based on the reports acted upon by the early jurists. Smiling, or laughing outside prayer, does not break wudu.

7. Direct skin contact of husband and wife in desire — the Hanafi school does not count mere touching as a nullifier (see below), keeping to the apparent meaning of the Quranic verse and the reports of the Prophet’s ﷺ conduct with his family.

Things That Do NOT Break Wudu

• Touching one’s private part — the Prophet ﷺ said: “It is only a part of your body.” (Jami’ at-Tirmidhi 85 · Sunan Abu Dawud 182 — Hasan)
• Touching a woman without desire, and mere touching in general in the Hanafi school.
• Eating or drinking, including cooked food — the Prophet ﷺ ate roasted meat and prayed without renewing wudu. (Sahih al-Bukhari 208 · Sahih Muslim 355)
• Blood that does not flow from the wound (see point 2 above).
• Doubting whether your wudu broke — certainty is not removed by doubt: “Let him not leave the mosque unless he hears a sound or smells an odour.” (Sahih al-Bukhari 137 · Sahih Muslim 361)
• Looking at anything, bad thoughts, or using impolite words — these affect manners, not wudu (deliberate backbiting etc. are sins but do not nullify wudu legally).

Common Questions

Does bleeding from a nosebleed break wudu?

Yes — nosebleed blood flows, so in the Hanafi school it breaks wudu.

I fell asleep sitting in the mosque. Must I repeat wudu?

If you were sitting firmly and grounded, your wudu remains valid (Sahih Muslim 376). If you were reclining or leaning unstably, renew it.

Does wudu break if I touch my baby while changing a nappy?

No. Touching impurity requires washing the impurity off the hand, but it does not by itself nullify wudu.

I am not sure whether I passed wind. What should I do?

Act on certainty: if you were sure you had wudu, remain on that certainty until you are sure it broke (Bukhari 137).

Conclusion

Learn these few rules once, and you will never be confused about your wudu again. When in genuine doubt, renewing wudu takes one minute — and it is itself an act of worship that washes away minor sins.
