Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates that the Prophet (peace and blessings be upon him) said: "Spitting in the mosque is a bad deed, and its expiation is burying it."
Al-Tabarani recorded it in al-Mu'jam al-Awsat; its chain contains a narrator, Muhammad bin Abi Layla, about whom there is criticism.
