باب وُجُوبِ الْقِرَاءَةِ لِلإِمَامِ وَالْمَأْمُومِ فِي الصَّلَوَاتِ كُلِّهَا فِي الْحَضَرِ وَالسَّفَرِ وَمَا يُجْهَرُ فِيهَا وَمَا يُخَافَتُ

Narrated 'Ubada bin As-Samit:

Allah's Messenger (ﷺ) said, "Whoever does not recite Al-Fatiha in his prayer, his prayer is invalid."

حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ، قَالَ حَدَّثَنَا سُفْيَانُ، قَالَ حَدَّثَنَا الزُّهْرِيُّ، عَنْ مَحْمُودِ بْنِ الرَّبِيعِ، عَنْ عُبَادَةَ بْنِ الصَّامِتِ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ لاَ صَلاَةَ لِمَنْ لَمْ يَقْرَأْ بِفَاتِحَةِ الْكِتَابِ ‏"‏‏.‏
