It is narrated from Sayyiduna Anas (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "The world is a prison for the believer and a paradise for the disbeliever."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Qatadah (may Allah have mercy on him) except Ayyub bin Khawt, and Dawud bin Mansur is alone in narrating it."
