10. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Marwak ibn ’Ubayd from Ahmad ibn al-Nadr from a man who has said the following: “Abu Ja‘far عليه السلام, once asked, ‘What do they say about a man who has missed two Rak‘at of the Imam’s Salah (prayer)?’ I replied, ‘They say that he is to recite al-Hamd and Surah (chapter) in them.’ He (the Imam) said, ‘He turns his Salah (prayer) backward by making its first the last.’ I then asked, ‘How is he to do it?’ He (the Imam) said, ‘He recites al-Fatihah al-Kitab in every Rak‘at.’”
