Sayyiduna al-Mustawrid bin Shaddad (may Allah be pleased with him) narrates: I heard the Prophet (peace and blessings be upon him) say: "Every nation has a fixed term, and the fixed term of my Ummah is one hundred years; when one hundred years have passed over my Ummah, there will come to them that which Allah Almighty has promised them." The narrator Ibn Lahi'ah says: This means the abundance of trials (fitan). Al-Tabarani recorded this report; its chain contains the narrator Ibn Lahi'ah, and despite his weakness he is hasan al-hadith (fair in narration).
