Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) reports this saying of the Prophet (peace and blessings be upon him): "By Allah, no one will come out of Hell until he has remained in it for 'ahqab' (ages)." He said: "One 'huqb' is eighty-odd years, each year of which is three hundred and sixty days, by your reckoning."
Al-Bazzar recorded it; its chain contains Sulayman bin Muslim al-Khashshab, who is extremely da'if (weak).
