Narrated Ubai bin Ka`b: I found a purse containing one hundred Diners. So I went to the Prophet (and informed him about it), he said, "Make public announcement about it for one year" I did so, but nobody turned up to claim it, so I again went to the Prophet who said, "Make public announcement for another year." I did, but none turned up to claim it. I went to him for the third time and he said, "Keep the container and the string which is used for its tying and count the money it contains and if its owner comes, give it to him; otherwise, utilize it." The sub-narrator Salama said, "I met him (Suwaid, another sub-narrator) in Mecca and he said, 'I don't know whether Ubai made the announcement for three years or just one year.' "

Narrated Suwaid bin Ghafala: While I as in the company of Salman bin Rabi`a and Suhan, in one of the holy battles, I found a whip. One of them told me to drop it but I refused to do so and said that I would give it to its owner if I found him, otherwise I would utilize it. On our return we performed Hajj and on passing by Medina, I asked Ubai bin Ka`b about it. He said, "I found a bag containing a hundred Dinars in the lifetime of the Prophet and took it to the Prophet who said to me, 'Make public announcement about it for one year.' So, I announced it for one year and went to the Prophet who said, 'Announce it publicly for another year.' So, I announced it for another year. I went to him again and he said, "Announce for an other year." So I announced for still another year. I went to the Prophet for the fourth time, and he said, 'Remember the amount of money, the description of its container and the string it is tied with, and if the owner comes, give it to him; otherwise, utilize it.' " Narrated Salama: the above narration (Hadith 616) from Ubai bin Ka`b: adding, "I met the sub-narrator at Mecca later on, but he did not remember whether Ka`b had announced what he had found one year or three years."

Narrated `Ali: I relate the traditions of Allah's Apostle to you for I would rather fall from the sky than attribute something to him falsely. But when I tell you a thing which is between you and me, then no doubt, war is guile. I heard Allah's Apostle saying, "In the last days of this world there will appear some young foolish people who will use (in their claim) the best speech of all people (i.e. the Qur'an) and they will abandon Islam as an arrow going through the game. Their belief will not go beyond their throats (i.e. they will have practically no belief), so wherever you meet them, kill them, for he who kills them shall get a reward on the Day of Resurrection."

Narrated `Ali: I heard the Prophet saying, "In the last days (of the world) there will appear young people with foolish thoughts and ideas. They will give good talks, but they will go out of Islam as an arrow goes out of its game, their faith will not exceed their throats. So, wherever you find them, kill them, for there will be a reward for their killers on the Day of Resurrection."

Narrated `Ali: Whenever I tell you a narration from Allah's Apostle, by Allah, I would rather fall down from the sky than ascribe a false statement to him, but if I tell you something between me and you (not a Hadith) then it was indeed a trick (i.e., I may say things just to cheat my enemy). No doubt I heard Allah's Apostle saying, "During the last days there will appear some young foolish people who will say the best words but their faith will not go beyond their throats (i.e. they will have no faith) and will go out from (leave) their religion as an arrow goes out of the game. So, where-ever you find them, kill them, for who-ever kills them shall have reward on the Day of Resurrection."
