The Book Pertaining to the Merits of the Companions (Allah Be Pleased With Them) of the Holy Prophet (May Peace Be Upon Him) (Kitab Al-Fada'il Al-Sahabah)
Muslim :: Book 31 : Hadith 6154
Abu Huraira reported Allah's Messenger (may, peace be upon him) as saying: The best age of my Umma is one in which I was sent (by Allah as an Apostle), then the one next to that. (The narrator said): And Allah knows best whether he stated this third (time) or not. Then there would come people who would love (to look) bulky and they would hasten to the witness box before they are asked to bear witness.
