Mukhtasar Muslim

Narrated from Sayyiduna Imran bin Husain (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: The best of you are those of my generation, then those who come after them, then those who come after them, then those who come after them. Sayyiduna Imran (may Allah be pleased with him) said: I do not know whether the Messenger of Allah (peace and blessings of Allah be upon him) mentioned two generations after his own or three. Then after them there will come people who will bear witness without being asked, will be treacherous and not trustworthy, will make vows but not fulfill them, and obesity will become widespread among them.
