It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that I heard the Prophet (peace and blessings of Allah be upon him) saying: People ask me about the Hour (Day of Judgment), although its true knowledge is only with Allah. However, I swear by Allah that none of those living today will remain alive after one hundred years.
