Performing Wudu' without saying Tasmiyah

Q: What is the ruling on someone who performs Wudu' (ablution), but does not mention the Name of Allah?

A: All praise be to Allah Alone, and peace and blessings be upon His Messenger, and his family and Companions. It is obligatory to utter Tasmiyah (saying, "Bismillah [In the Name of Allah]") at the time of performing Wudu’, but if anyone performs it without mentioning the Name of Allah, through forgetfulness or ignorance of the legal ruling, their ablution is still valid. However, if anyone omits it deliberately, their Wudu’ is invalid, according to the more correct of the two scholarly opinions, based on the Hadith of the Prophet (peace be upon him): (Part No. 5; Page No. 204) “No Wudu’ (is valid) for the one who has not mentioned the Name of Allah upon it.” (Related by Ahmad, Abu Dawud, and Ibn Majah through many chains of narrators, supporting one another)May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
