Actually, Pakistani Taliban leader Mullah Fazlullah, tried to convince his followers against many things. He began daily sermons on illegal FM frequencies, where he used to spread his messages throughout the region.
These were hate speeches against the Americans, the Pakistani state, female education, the Polio vaccine, and promulgating the militant's extreme interpretation of Sharia law.
Because of these believes, he used to say people shouldn't agree or help in any way to give power to all those things he was against to.
Some, after listening to his sermons, threw their television sets out because he described them as "<em>un-Islamic</em>". Many "<em>Swatis</em>" grew beards because of his lectures.
Urban means city or surrounded by many. Rural means country or secluded (set off by itself). Therefore, these two are antonyms. A synonym for Urban would be city, crowded, large population. A synonym for Rural would be country, seclusion, less populated. Since antonyms are the opposite, that makes urban and rural antonyms.
The answer is focusing on the concrete elements that can be directly pointed out.
