Answered by Shaykh Faraz Rabbani
If you are unsure about whether or not your wudu is broken, you DON’T have to do it again. If you are sure of having done wudu correctly once, you only have to do it again if you are sure of having broken it. Is this correct?
Walaikum assalam,
Correct. There have being several posts explaining the fiqh of doubt and certainty. Search the Hanafi list archives at for “doubt certainty”
Wassalam, your brother,
