Hadith 818
Chapter 287: The One Who Did Not Recite The Faithah In His Prayer - كتاب الصلاة
حَدَّثَنَا أَبُو الْوَلِيدِ الطَّيَالِسِيُّ، حَدَّثَنَا هَمَّامٌ، عَنْ قَتَادَةَ، عَنْ أَبِي نَضْرَةَ، عَنْ أَبِي سَعِيدٍ، قَالَ أُمِرْنَا أَنْ نَقْرَأَ، بِفَاتِحَةِ الْكِتَابِ وَمَا تَيَسَّرَ .
Abu sa’id said:
we were commanded to recite Fatihat al-kitab and whatever was convenient (from the Qur’an during the prayer).
