Sayyiduna Abdullah bin Amr (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said: "Whoever falls asleep while sitting, ablution is not obligatory upon him; but when he lays his side down (on the ground), ablution is obligatory upon him."
Al-Tabarani recorded it in al-Mu'jam al-Awsat; its chain contains a narrator, al-Hasan bin Abi Ja'far al-Jufri, whom al-Bukhari (may Allah have mercy on him) and others declared da'if (weak). Ibn Adi says: Sound hadith are reported from him, and he does not lie deliberately.
