[WumibBesowe]

what is mad'hur?

A ma'dhur is the person who is excused, and can pray without performing wudu twice. He will only need to perform wudu once, once the time for prayer has set in. The conditions:

In principle, if you are unable to keep your wuzu for at least two rakats salah and this state remains for at least one entire salah duration, for example between Asr and Maghrib, then you are a ma’zoor.
http://www.askimam.org/fatwa/fatwa.p...37af11554d9611 If you are asking regarding when a person is rendered a mazoor, then:- One will only be regarded as mazoor, when one does not have sufficient time to perform his wudhu and just the fard salaat, due to the uzar ceasing to stop for the whole salaat time. ( Hashia of Nurul-Eidha )

If you are asking regarding the termination of one being a mazoor, then; One will no longer be a mazoor when the uzar stops completely for one full salaat time. (Nurul-eidha)
