If for whatever reason I am not content with the way I did my wiping of the feet or head, whether it be because I have doubt that i did it correctly or some other reason.

Can I repeat the process of the wiping? Must it be done once? Or should you restart the wudu from the beginning if the sequence is important?

Must be restarted from the beginning

However if it getting too much doubts then the doubts must be ignored
