The Messenger of Allah ﷺ said: He who does not recite Umm al-Qur'an is not credited with having observed the prayer.  

قَالَ رَسُولُ اللَّهِ ﷺ لاَ صَلاَةَ لِمَنْ لَمْ يَقْتَرِئْ بِأُمِّ الْقُرْآنِ  

"The Messenger of Allah ﷺ said: "There is no Salah for one who does not recite Fatihatil-Kitab or more.'" (Using translation from Nasāʾī 911)   

قَالَ رَسُولُ اللهِ ﷺ لَا صَلَاةَ لِمَنْ لَمْ يَقْرَأْ بِأُمِّ الْقُرْآنِ فَصَاعِدًا  

“I heard the Messenger of Allah ﷺ say: ‘Every prayer in which the Ummul-Kitab (the Mother of the Book) is not recited is deficient.’” (Using translation from Ibn Mājah 840)   

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ مَنْ صَلَّى صَلَاةً لَمْ يَقْرَأْ فِيهَا بِأُمِّ الْقُرْآنِ فَهِيَ خِدَاجٌ  

"The Messenger of Allah ﷺ said: "There is no Salah for one who does not recite Fatihatil-Kitab or more.'" (Using translation from Nasāʾī 911)   

قَالَ رَسُولُ اللَّهِ ﷺ «لَا صَلَاةَ لِمَنْ لَمْ يَقْرَأْ بِأُمِّ الْقُرْآنِ فَصَاعِدًا»  

"The Messenger of Allah ﷺ said: "There is no Salah for one who does not recite Fatihatil-Kitab or more.'" (Using translation from Nasāʾī 911)   

قَالَ رَسُولُ اللَّهِ ﷺ «لَا صَلَاةَ لِمَنْ لَمْ يَقْرَأْ بِأُمِّ الْقُرْآنِ فَصَاعِدًا»  

"مَنْ لَمْ يَقْرَأ مَعَ الإِمَامِ فصَلاتُهُ خِدَاجٌ".  

"كُل صَلاة لا يقرأ فيهَا بأمِّ القرآن فهي خداجٌ".  

"لَا صَلَاةَ لِمَنْ لَمْ يَقْرَأ بِأُمِّ الْقُرآنِ فَصَاعِدًا (*) ".
