Hudhaifa reported that Allah's Messenger (ﷺ) stood before us one day and he did not leave anything unsaid (that he had to say) at that very spot which would happen (in the shape of turmoil) up to the Last Hour. Those who had to remember them preserved them in their minds and those who could not remember them forgot them. My friends knew them and there are certain things which slip out of my mind, but I recapitulate them when anyone makes a mention of them just as a person is lost from one's mind but is recalled to him on seeing his face.
