Fasting
Question
Mufti, i would like to know if it is permissible to brush your teeth using toothpaste while fasting? As long as nothing goes down your throat when brushing your teeth, then is the fast valid?
Answer
Assalamu Alaykum Warahmatullah.

It is Makhrooh (reprehensible) to use toothpaste during fasting even though the paste does not go down the throat.
And Allah Knows Best
Mufti Ebrahim Desai
