In this hadith, the Prophet (blessings and peace of Allah be upon him) spoke of a matter of the unseen of which Allah had informed him, as ‘Abdullah ibn ‘Umar (may Allah be pleased with him) narrated that the Prophet (blessings and peace of Allah be upon him) led them in praying ‘Isha’ one day at the end of his life. According to a report narrated by Muslim from Jabir ibn ‘Abdillah (may Allah be pleased with him), that happened one month before he died. When he said the salaam and finished his prayer, he turned to them and exhorted them, and he told them that after one hundred years had passed, there would be no one left on the face of the earth who was alive on that night. And this is what happened. Even though some of those people lived to a great age, none of them were left alive one hundred years after that night on which the Prophet (blessings and peace of Allah be upon him) told them of that. That was a reminder to them that life is short. Thus he informed them that they would not live as long as the nations who came before them, so that they would strive hard. This hadith is one of the signs of the prophethood of the Prophet (blessings and peace of Allah be upon him)..
