It is narrated from Sayyiduna Jubayr bin Mut'im (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Indeed Allah, the Mighty and Majestic, afflicts His servant with illness until He wipes away all of his sins."
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is not narrated from Jubayr bin Mut'im (may Allah be pleased with him) except with this chain; Ya'qub bin Abd al-Rahman is alone in narrating it."
