ذِكْرُ إِيقَاعِ النَّقْصِ عَلَى الصَّلَاةِ إِذَا لَمْ يُقْرَأْ فِيهَا بِفَاتِحَةِ الْكِتَابِ

[Machine] The Messenger of Allah ﷺ said: "Every prayer in which Al-Fatiha (the opening chapter of the Quran) is not recited is incomplete, every prayer in which Al-Fatiha is not recited is incomplete, every prayer in which Al-Fatiha is not recited is incomplete."  

ابن حبّان:١٧٨٨ – أَخْبَرَنَا أَبُو قُرَيْشٍ مُحَمَّدُ بْنُ جُمُعَةَ الْأَصَمُّ الْحَافِظُ قَالَ حَدَّثَنَا عَبْدُ اللَّهِ بْنُ سَعِيدٍ الْكِنْدِيُّ قَالَ حَدَّثَنَا عُقْبَةُ بْنُ خَالِدٍ قَالَ حَدَّثَنَا سَعْدُ بْنُ سَعِيدٍ عَنِ الْعَلَاءِ بْنِ عَبْدِ الرَّحْمَنِ عَنْ أَبِيهِ عَنْ أَبِي هُرَيْرَةَ قَالَ

قَالَ رَسُولُ اللَّهِ ﷺ «كُلُّ صَلَاةٍ لَا يُقْرَأُ فِيهَا بِفَاتِحَةِ الْكِتَابِ فَهِيَ خِدَاجٌ كُلُّ صَلَاةٍ لَا يُقْرَأُ فِيهَا بِفَاتِحَةِ الْكِتَابِ فَهِيَ خِدَاجٌ كُلُّ صَلَاةٍ لَا يُقْرَأُ فِيهَا بِفَاتِحَةِ الْكِتَابِ فَهِيَ خِدَاجٌ»
