Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) narrates this saying of the Prophet (peace and blessings be upon him): "If an iron mace (of Hell) were placed on the earth and the two races (that is, humans and jinn) gathered to lift it, they would not be able to move it from the earth."
Ahmad and Abu Ya'la recorded it; its chain contains weak narrators who have been declared trustworthy.
