Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 57
وَقَالَ أَبُو جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ لِرَجُلٍ «أَيَّ شَيْءٍ يَقُولُ هَؤُلاَءِ فِي اَلرَّجُلِ إِذَا فَاتَتْهُ مَعَ اَلْإِمَامِ اَلرَّكْعَتَانِ» قُلْتُ يَقُولُونَ يَقْرَأُ فِي اَلرَّكْعَتَيْنِ بِالْحَمْدِ وَ سُورَةٍ فَقَالَ «هَذَا يُقَلِّبُ صَلاَتَهُ فَيَجْعَلُ أَوَّلَهَا آخِرَهَا» قُلْتُ فَكَيْفَ يَصْنَعُ قَالَ «يَقْرَأُ فَاتِحَةَ اَلْكِتَابِ فِي كُلِّ رَكْعَةٍ.
Imam Muhammad ibn Ali Al-Baqir عليه السلام sked a man: "What do these people say about a person who misses two rak'ahs with the Imam?" The man replied: "They say he should recite Al-Hamd (Surah Al-Fatiha) and a Surah in the two rak'ahs." Imam عليه السلام said: "This would reverse his prayer, making the beginning the end." The man then asked: "So what should he do?" Imam عليه السلام replied: "He should recite Surah Al-Fatiha in each rak'ah”.
