What was narrated by al-Husayn ibn Sa’id from Uthman ibn ‘Isa from Sama’ah, who said: I asked Him عليه السلام about a man who stands in prayer and forgets Surat al-Fatihah. Imam عليه السلام said: "Let him say: ‘I seek refuge in Allah سبحانه وتعالى from the accursed Shaytan. Indeed, Allah سبحانه وتعالى is the All-Hearing, the All-Knowing,’ then let him recite it as long as he has not bowed. For there is no (valid) recitation until he begins with it, whether aloud or silently. But if he has bowed, it suffices him, if Allah سبحانه وتعالى, the Exalted, wills."
