Narrated 'Imran bin Husain (RA): Allah's Messenger (ﷺ) said: "Verily! The best of you (i.e. Muslims) are my generation, then their immediate followers, then their immediate followers. After them there will be people who will give (false) testimony without being asked (to testify), who will be treacherous and are not to be trusted, who will make vows and will not fulfill them, among whom obesity will appear." [Agreed upon].
