Sayyiduna Abdullah bin Amr (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "The signs of the Hour are like beads arranged in a string; if the string breaks, (the beads) fall one after another in succession."

It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Noble Prophet, peace and blessings be upon him, said: "Just as when a string (breaks), its beads start falling one after another in succession, in the same way, the signs of the Hour will appear one after another in succession."
