Answered by Shaykh Faraz Rabbani
Every night, I need to use an alcohol-free prescription dental mouthwash (containing Stannous Fluoride) which requires that I do not rinse my mouth with water for 30 minutes after use. Does using this prescription dental mouthwash invalidate my wudu (as in, would I not be able to pray during the 30 minute period in which I cannot rinse my mouth, for the purposes of making wudu)?

Assalamu alaikum wa rahmatullah,
I pray this finds you in the best of health and spirits.
No, such mouthwash would not affect your wudu. Please search SunniPath Answers (http://qa.sunnipath.com) for related answers on (1) that which invalidates wudu; and (2) using alcohol-based mouthwash.
And Allah alone gives success.
