Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates that the Prophet (peace and blessings be upon him) said: "Whoever does not place his nose on the ground along with his forehead when he prostrates, his prayer is not valid."
Imam al-Tabarani recorded it in al-Mu'jam al-Kabir and al-Mu'jam al-Awsat; its narrators have been declared trustworthy, although there is disagreement about some of its narrators because of their Shi'ism.
