It is narrated from Sayyiduna al-Mustawrid bin Shaddad (may Allah be pleased with him): I heard the Messenger of Allah (peace and blessings be upon him) say: "Every nation has an appointed time and a term, and indeed the term of my Ummah (for this particular era) is one hundred years. So when one hundred years have passed over my Ummah, there will come to it that (decision or command of Allah) which Allah, the Mighty and Majestic, has promised it."
The chain of this hadith contains the narrator Abdullah bin Lahi'ah, who is da'if (weak) in respect of memory; however, its meaning, that after a hundred years have passed no one alive at that time will remain, is established and supported by sahih hadith.
