Does laughter invalidate Salah?

Q 4: Some people claim that smiling invalidates Salah (Prayer) while laughter invalidates both Wudu' (ablution) and Salah, is this true?

A: Laughing, not merely smiling, invalidates Salah, but it does not invalidate Wudu' whether it happens during or outside Salah, for lack of evidence in this regard.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
