How can one overcome the problem of uncontrollable flatulence in a non-Islamic country where there is no place for Wudu or prayer? Is it permissible to combine prayers with a single Wudu, or to follow the Maliki school of thought in such a situation?

You are permitted to act according to the Maliki school of thought in this matter if you find yourself in a difficult situation. The Hanbalis, furthermore, allow a person afflicted with urinary incontinence to combine two prayers during the time of one of them. This school of thought offers ease and leniency.
