Narrated to us Muhammad ibn al-Muthanna and Ibn Bashshar—Ibn al-Muthanna said: narrated to us Muhammad ibn Ja'far: narrated to us Shu'bah, who said: I heard Qatadah narrating from Anas ibn Malik, who said: The Messenger of Allah, peace and blessings be upon him, said: "When one of you is in prayer, he is in private conversation with his Lord, so let him not spit in front of him or to his right, but rather to his left, beneath his foot."
