And as for what was narrated by Sa‘d bin Abdillah, from Ahmad bin al-Hasan bin Ali bin Faddal, from ‘Amr bin Sa‘id al-Mada’ini, from Musaddiq bin Sadaqah, from ‘Ammar bin Musa al-Sabati, from Abu Abdillah عليه السلام (peace be upon him), who said: I asked Him عليه السلام about the two prostrations of forgetfulness (‘sajdatay al-sahw’), is there in them any ‘takbir’ (saying "Allahu Akbar") or ‘tasbih’ (glorification)? Imam عليه السلام said: "No, they are only two prostrations. But if the one who erred is the imam (of prayer), then he says ‘takbir’ when he goes into prostration and when he raises his head, in order to inform those behind him that he has made an error. He is not required to say ‘tasbih’ in them, and there is no ‘tashahhud’ after the two prostrations."
