Answer
(Fatwa: 417/J)
Only with doubt and suspicion the wuzu does not break. Do not break your salah (prayer) until you are sure that your wuzu is nullified. You will be considered mazoor only when you do not find a time in which you perform wuzu and pray farz salah without passing gas. During this if the gas passing continues or occurs occasionally then you will be considered mazoor. And, a mazoor is allowed to perform one wuzu in a time of salah and then perform whatever salah and aamaal you like during this time and by passing gas your wuzu will not break. But, in order to remain mazoor it is necessary that the uzr (i.e. passing gas) occurs at least once, if it does not occur even once in a salah time then you shall not remain mazoor.
