It is narrated from Sayyiduna al-Mughirah bin Shu'bah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) recited the tashahhud after raising his head from the two prostrations of forgetfulness (sajdat al-sahw).
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from al-Sha'bi except Ibn Abi Layla, and his son is alone in narrating it from him."
