Q 2: One of the Ma'mums (people being led by an Imam in Prayer) yawned widely. After Salah (Prayer), a man claimed that
yawning during Salah without covering the mouth invalidates Wudu' (ablution). Is this true?
Please advise, may Allah reward you.
It is prescribed for those who yawn to cover their mouths. It was authentically reported from
Abu Sa`id Al-Khudry (may Allah be pleased with him) that the Messenger of Allah (peace be upon him) said,
When one of you yawns, you should cover your mouth with your hand.
Otherwise, Satan will enter inside you. However, yawning does not invalidate Wudu'.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
