Sayyiduna Sufyan bin Wahb al-Khawlani (may Allah be pleased with him) narrates: I heard the Prophet (peace and blessings be upon him) say: "By the time one hundred years have passed, no one will remain on the face of the earth."
Al-Tabarani recorded it in al-Mu'jam al-Kabir. Its narrator Sa'id bin Abi Shimr was mentioned by Ibn Abi Hatim, who said: He narrated from his father, and Abu Bakr bin Sawad narrated from him. However, Abd al-Rahman bin Shurayh has also narrated from him, and no one has declared him weak. The rest of its narrators have been declared trustworthy.
