What Breaks Salah
Once you have started the prayer (with the takbir al-ihram), certain actions invalidate it. If they happen, the prayer must be restarted.
What invalidates the prayer
1. Talking deliberately
Any spoken word unrelated to the prayer, even briefly, invalidates the prayer. This includes speaking to someone, answering a question, or saying a worldly word.
(Unintentional words from sneezing/coughing reflexes do not break it.)
2. Laughing out loud
Audible laughter breaks the salah. A silent smile does not break it.
3. Eating or drinking
Any food or drink, even a small amount, breaks the prayer. Swallowing the remnants of food already in the mouth (so small it cannot be expelled) does not break it.
4. Major movement unrelated to the prayer
The standard among many scholars is three or more consecutive non-prayer movements that suggest the person is no longer engaged in salah. A single quick movement (adjusting clothing, scratching, brushing a fly) does not break it.
5. Intentionally turning the chest away from the qibla
A small turn of the head while staying generally aligned with the qibla is fine. Deliberately rotating your whole body away breaks the prayer.
6. Losing wudu mid-prayer
If your wudu is broken during the salah (passing wind, etc.), by the very fact of losing wudu, the prayer is invalid. Leave the prayer, renew wudu, and start over.
7. Intentionally adding a rakah or omitting a pillar
If you knowingly add an extra rak’ah or skip an essential part (a rukn) like ruku or sujood, the prayer is invalid.
(For unintentional addition or omission, perform sujood al-sahw, the prostration of forgetfulness, and the prayer remains valid.)
8. Najasah you become aware of
If you discover (or it falls onto you) physical impurity on your body, clothes, or place of prayer, the prayer is invalidated. (If you only discover it after finishing, your prayer was still valid per the stronger position.)
9. Apostasy
If a person leaves Islam during the prayer (refusing it, mocking it, etc.), the prayer is invalidated. Mentioned for completeness.
What does NOT break salah
- Small movements, scratching an itch, adjusting a child, brushing a fly. The Prophet ﷺ used to carry his granddaughter Umama in prayer.
- Silent prayer for someone in your du’a section (allowed)
- Crying or being moved during recitation (from khushu’ / awe of Allah)
- A small unconscious shift in posture
- Swallowing saliva or food remnants too small to expel
- Smiling silently
- A short cough or sneeze
- Forgetting whether you are in rak’ah 2 or 3, go with the lower count and do sujood al-sahw
If you make a mistake, sujood al-sahw
For unintentional errors during the prayer (forgetting the first tashahhud, adding an extra movement by mistake, doubt about the rak’ah count), there is a built-in correction: sujood al-sahw, two extra prostrations performed at the end of the prayer.
A dedicated page on sujood al-sahw with the specific cases and how to perform it is coming.
For now: if you notice you made a mistake during prayer, complete the prayer normally and add two prostrations at the end (after the final tashahhud, before tasleem, or after tasleem, depending on the case). The prayer is then valid.
