Muhammad ibn Ya‘qub from Ali ibn Muhammad from Muhammad ibn ‘Isa from Yunus from al-’Alaʾ from Muhammad ibn Muslim, who said: I asked Him عليه السلام about the one who does not recite Surat al-Fatihah in his prayer. Imam عليه السلام said: "There is no prayer for him unless he begins with it, whether aloud or silently." I said: "Which of the two do you prefer: if he is fearful or in a hurry, should he recite a (different) Surah or Surat al-Fatihah?" Imam عليه السلام said: "Surat al-Fatihah."
