It is narrated from Sayyiduna Abu Dharr (may Allah be pleased with him) that he used to serve the Prophet (peace and blessings be upon him), and when he finished serving him (peace and blessings be upon him), he would come to the mosque and lie down there.
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is narrated from Sayyiduna Abu Dharr (may Allah be pleased with him) only through this chain, and Isma'il bin Ayyash is alone in narrating it."
