Hammad said: I asked Ibrahim about a man who forgets to recite Surah al-Fatihah in the prayer but recites another surah, or recites Surah al-Fatihah but does not recite another surah with it: what is the ruling on his prayer? Ibrahim said: "His prayer is valid."

Jabir said: Amir (al-Sha'bi) and al-Hakam were asked about a man who forgets to recite Surah al-Fatihah in the prayer. Al-Sha'bi said: "He should perform the prostrations of forgetfulness (sajdah al-sahw)," and al-Hakam said: "He should recite Surah al-Fatihah when he remembers."

Al-Hasan said, regarding a man who forgets Surah al-Fatihah but recites Surah al-Ikhlas: "His prayer is valid."
