The best of you are my generation, then those who follow them, then those who will come after them. Then, they will be followed by those who will testify but will not be called upon to testify; they will betray the trust, and will not be trusted. They will make vows but will not fulfill them, and obesity will prevail among them.

- Bukhari and Muslim.Riyad-us-Saliheen (Chapter 56, Hadith # 509)
