Having Doubts Regarding Purification in Salah
As-Salamu `alaykum. Very often when I stand up to pray, I have doubts in my mind as to whether my purification or wudu' has been nullified or not. What should I do in such a situation: Should I leave the salah and purify myself and then resume my salah, or should I simply continue my salah and not bother about such doubts?
