Sayyiduna Abu Dharr Ghifari (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) said: "The good and bad deeds of my Ummah were presented before me. Among their good deeds, I found the removal of something harmful from the road, and among their bad deeds, I found the spittle that was in the mosque and had not been buried."
