Imran b. Husain reported God's messenger as saying, "The best of my people are my generation, then their immediate followers, then their immediate followers. After them there will be people who give testimony without being asked, who will be treacherous and not to be trusted, who will make vows which they do not fulfil, among whom fatness [*] will appear." A version has "They will swear oaths without being asked to do so." *Mirqat 5:520 f., gives various explanations of this, including unjustified pride, unjustified claims to nobility, acquisition of wealth, elaborate food and drink, neglect of religious duties. It is obviously some unsatisfactory characteristic which is intended. The various meanings suggested might be combine by treating it as meaning fine living which leads to neglect of religion. (Bukhari and Muslim.)
