He who does not recite Fatihat al-Kitab is not credited with having observed the prayer.  

النَّبِيَّ ﷺ لاَ صَلاَةَ لِمَنْ لَمْ يَقْرَأْ بِفَاتِحَةِ الْكِتَابِ  

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  

He who does not recite Umm al-Qur'an is not credited with having observed prayer.  

أَنَّ مَحْمُودَ بْنَ الرَّبِيعِ الَّذِي مَجَّ رَسُولُ اللَّهِ ﷺ فِي وَجْهِهِ مِنْ بِئْرِهِمْ أَخْبَرَهُ أَنَّ عُبَادَةَ بْنَ الصَّامِتِ أَخْبَرَهُ أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ صَلاَةَ لِمَنْ لَمْ يَقْرَأْ بِأُمِّ الْقُرْآنِ  

" and something more".  

عَنِ الزُّهْرِيِّ بِهَذَا الإِسْنَادِ مِثْلَهُ وَزَادَ فَصَاعِدًا  

The Apostle of Allah ﷺ said: If anyone observes prayer in which he does not recite Umm al-Qur'an, It is deficient [he said this three times] and not complete. It was said to Abu Huraira: At times we are behind the Imam. He said: Recite it inwardly, for he had heard the Messenger of Allah ﷺ declare that Allah the Exalted had said: I have divided the prayer into two halves between Me and My servant, and My servant will receive what he asks. When the servant says: Praise be to Allah, the Lord of the universe, Allah the Most High says: My servant has praised Me. And when he (the servant) says: The Most Compassionate, the Merciful, Allah the Most High says: My servant has lauded Me. And when he (the servant) says: Master of the Day of judg- ment, He remarks: My servant has glorified Me. and sometimes He would say: My servant entrusted (his affairs) to Me. And when he (the worshipper) says: Thee do we worship and of Thee do we ask help, He (Allah) says: This is between Me and My servant, and My servant will receive what he asks for. Then, when he (the worshipper) says: Guide us to the straight path, the path of those to whom Thou hast been Gracious not of those who have incurred Thy displeasure, nor of those who have gone astray, He (Allah) says: This is for My servant, and My servant will receive what he asks for. Sufyan said: 'Ala b. 'Abd al-Rahman b. Ya'qub narrated it to me when I went to him and he was confined to his home on account of illness, and I asked him about it.  

عَنِ النَّبِيِّ ﷺ قَالَ مَنْ صَلَّى صَلاَةً لَمْ يَقْرَأْ فِيهَا بِأُمِّ الْقُرْآنِ فَهْىَ خِدَاجٌ ثَلاَثًا غَيْرُ تَمَامٍ فَقِيلَ لأَبِي هُرَيْرَةَ إِنَّا نَكُونُ وَرَاءَ الإِمَامِ فَقَالَ اقْرَأْ بِهَا فِي نَفْسِكَ فَإِنِّي سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ قَالَ اللَّهُ تَعَالَى قَسَمْتُ الصَّلاَةَ بَيْنِي وَبَيْنَ عَبْدِي نِصْفَيْنِ وَلِعَبْدِي مَا سَأَلَ فَإِذَا قَالَ الْعَبْدُ { الْحَمْدُ لِلَّهِ رَبِّ الْعَالَمِينَ} قَالَ اللَّهُ تَعَالَى حَمِدَنِي عَبْدِي وَإِذَا قَالَ { الرَّحْمَنِ الرَّحِيمِ} قَالَ اللَّهُ تَعَالَى أَثْنَى عَلَىَّ عَبْدِي وَإِذَا قَالَ { مَالِكِ يَوْمِ الدِّينِ} قَالَ مَجَّدَنِي عَبْدِي وَقَالَ مَرَّةً فَوَّضَ إِلَىَّ عَبْدِي فَإِذَا قَالَ { إِيَّاكَ نَعْبُدُ وَإِيَّاكَ نَسْتَعِينُ} قَالَ هَذَا بَيْنِي وَبَيْنَ عَبْدِي وَلِعَبْدِي مَا سَأَلَ فَإِذَا قَالَ { اهْدِنَا الصِّرَاطَ الْمُسْتَقِيمَ * صِرَاطَ الَّذِينَ أَنْعَمْتَ عَلَيْهِمْ غَيْرِ الْمَغْضُوبِ عَلَيْهِمْ وَلاَ الضَّالِّينَ} قَالَ هَذَا لِعَبْدِي وَلِعَبْدِي مَا سَأَلَ قَالَ سُفْيَانُ حَدَّثَنِي بِهِ الْعَلاَءُ بْنُ عَبْدِ الرَّحْمَنِ بْنِ يَعْقُوبَ دَخَلْتُ عَلَيْهِ وَهُوَ مَرِيضٌ فِي بَيْتِهِ فَسَأَلْتُهُ أَنَا عَنْهُ  

He who observed prayer but he did not recite the Umm al-Qur'an in it, and the rest of the hadith is the same as transmitted by Sufyan, and in this hadith the words are:" Allah the Most High said: the prayer is divided into two halves between Me and My servant. The half of it is for Me and the half of it is for My servant."  

قَالَ رَسُولُ اللَّهِ ﷺ ح وَحَدَّثَنِي مُحَمَّدُ بْنُ رَافِعٍ حَدَّثَنَا عَبْدُ الرَّزَّاقِ أَخْبَرَنَا ابْنُ جُرَيْجٍ أَخْبَرَنِي الْعَلاَءُ بْنُ عَبْدِ الرَّحْمَنِ بْنِ يَعْقُوبَ أَنَّ أَبَا السَّائِبِ مَوْلَى بَنِي عَبْدِ اللَّهِ بْنِ هِشَامِ بْنِ زُهْرَةَ أَخْبَرَهُ أَنَّهُ سَمِعَ أَبَا هُرَيْرَةَ يَقُولُ قَالَ رَسُولُ اللَّهِ ﷺ مَنْ صَلَّى صَلاَةً فَلَمْ يَقْرَأْ فِيهَا بِأُمِّ الْقُرْآنِ بِمِثْلِ حَدِيثِ سُفْيَانَ وَفِي حَدِيثِهِمَا قَالَ اللَّهُ تَعَالَى قَسَمْتُ الصَّلاَةَ بَيْنِي وَبَيْنَ عَبْدِي نِصْفَيْنِ فَنِصْفُهَا لِي وَنِصْفُهَا لِعَبْدِي  

The Messenger of Allah ﷺ said: He who said his prayer, but did not recite the opening chapter of al-Kitab, his prayer is incomplete. He repeated it thrice.  

سَمِعْتُ مِنْ أَبِي وَمِنْ أَبِي السَّائِبِ وَكَانَا جَلِيسَىْ أَبِي هُرَيْرَةَ قَالاَ قَالَ أَبُو هُرَيْرَةَ قَالَ رَسُولُ اللَّهِ ﷺ مَنْ صَلَّى صَلاَةً لَمْ يَقْرَأْ فِيهَا بِفَاتِحَةِ الْكِتَابِ فَهْىَ خِدَاجٌ يَقُولُهَا ثَلاَثًا بِمِثْلِ حَدِيثِهِمْ  

The Messenger of Allah ﷺ said: One is not credited with having observed the prayer without the recitation (of al-Fatiha). So said Abu Huraira: (The prayer in which) the Messenger of Allah ﷺ recited in a loud voice, we also recited that loudly for you (and the prayer in which) he recited inwardly we also recited inwardly for you (to give you a practical example of the prayer of the Holy Prophet).  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ صَلاَةَ إِلاَّ بِقِرَاءَةٍ قَالَ أَبُو هُرَيْرَةَ فَمَا أَعْلَنَ رَسُولُ اللَّهِ ﷺ أَعْلَنَّاهُ لَكُمْ وَمَا أَخْفَاهُ أَخْفَيْنَاهُ لَكُمْ  

If I add nothing to the (recitation) of the Umm al Qur'an (Surat al-Fatiha), would it make the prayer incomplete? He (AbuHuraira) said: If you add to that (if you recite some of verses of the Qur'an along with Surat at-Fatiha) that is better for you. But if you are contented with it (Surat al-Fatiha) only, it is sufficient for you.  

أَبُو هُرَيْرَةَ فِي كُلِّ الصَّلاَةِ يَقْرَأُ فَمَا أَسْمَعَنَا رَسُولُ اللَّهِ ﷺ أَسْمَعْنَاكُمْ وَمَا أَخْفَى مِنَّا أَخْفَيْنَا مِنْكُمْ فَقَالَ لَهُ رَجُلٌ إِنْ لَمْ أَزِدْ عَلَى أُمِّ الْقُرْآنِ فَقَالَ إِنْ زِدْتَ عَلَيْهَا فَهُوَ خَيْرٌ وَإِنِ انْتَهَيْتَ إِلَيْهَا أَجْزَأَتْ عَنْكَ  

Recitation (of Surat al-Fatiha) in every (rak'ah) of prayer in essential. (The recitation) that we listened to from the Messenger of Allah ﷺ we made you listen to it. And that which he recited inwardly to us, we recited it inwardly for you. And he who recites Umm al-Qur'an, it is enough for him (to complete the prayer), and he who adds to it (recites some other verses of the Holy Qur'an along with Surat al-Fatiha), it is preferable for him.  

أَبُو هُرَيْرَةَ فِي كُلِّ صَلاَةٍ قِرَاءَةٌ فَمَا أَسْمَعَنَا النَّبِيُّ ﷺ أَسْمَعْنَاكُمْ وَمَا أَخْفَى مِنَّا أَخْفَيْنَاهُ مِنْكُمْ وَمَنْ قَرَأَ بِأُمِّ الْكِتَابِ فَقَدْ أَجْزَأَتْ عَنْهُ وَمَنْ زَادَ فَهُوَ أَفْضَلُ  

The Messenger of Allah ﷺ entered the mosque and a person also entered therein and offered prayer, and then came and paid salutation to the Messenger of Allah ﷺ. The Mes- senger of Allah ﷺ returned his salutation and said: Go back and pray, for you have not offered the prayer. He again prayed as he had prayed before, and came to the Messenger of Allah (may peace be upon. him) and saluted him. The Messenger of Allah ﷺ returned the salutation and said: Go back and say prayer, for you have not offered the prayer. This (act of repeating the prayer) was done three times. Upon this the person said: By Him Who hast sent you with Truth, whatever better I can do than this, please teach me. He (the Holy Prophet) said: When you get up to pray, recite takbir, and then recite whatever you conveniently can from the Qur'an, then bow down and remain quietly in that position, then raise your- self and stand erect; then prostrate yourself and remain quietly in that attitude; then raise yourself and sit quietly; and do that throughout all your prayers.  

أَنَّ رَسُولَ اللَّهِ ﷺ دَخَلَ الْمَسْجِدَ فَدَخَلَ رَجُلٌ فَصَلَّى ثُمَّ جَاءَ فَسَلَّمَ عَلَى رَسُولِ اللَّهِ ﷺ فَرَدَّ رَسُولُ اللَّهِ ﷺ السَّلاَمَ قَالَ ارْجِعْ فَصَلِّ فَإِنَّكَ لَمْ تُصَلِّ فَرَجَعَ الرَّجُلُ فَصَلَّى كَمَا كَانَ صَلَّى ثُمَّ جَاءَ إِلَى النَّبِيِّ ﷺ فَسَلَّمَ عَلَيْهِ فَقَالَ رَسُولُ اللَّهِ ﷺ وَعَلَيْكَ السَّلاَمُ ثُمَّ قَالَ ارْجِعْ فَصَلِّ فَإِنَّكَ لَمْ تُصَلِّ حَتَّى فَعَلَ ذَلِكَ ثَلاَثَ مَرَّاتٍ فَقَالَ الرَّجُلُ وَالَّذِي بَعَثَكَ بِالْحَقِّ مَا أُحْسِنُ غَيْرَ هَذَا عَلِّمْنِي قَالَ إِذَا قُمْتَ إِلَى الصَّلاَةِ فَكَبِّرْ ثُمَّ اقْرَأْ مَا تَيَسَّرَ مَعَكَ مِنَ الْقُرْآنِ ثُمَّ ارْكَعْ حَتَّى تَطْمَئِنَّ رَاكِعًا ثُمَّ ارْفَعْ حَتَّى تَعْتَدِلَ قَائِمًا ثُمَّ اسْجُدْ حَتَّى تَطْمَئِنَّ سَاجِدًا ثُمَّ ارْفَعْ حَتَّى تَطْمَئِنَّ جَالِسًا ثُمَّ افْعَلْ ذَلِكَ فِي صَلاَتِكَ كُلِّهَا  

A person entered the mosque and said prayer while the Messenger of Allah ﷺ was sitting in a nook (of the mosque), and the rest of the hadith is the same as mentioned above, but with this addition:" When you get up to pray, perform the ablution completely, and then turn towards the Qibla and recite takbir (Allah o Akbar =Allah is the Most Great)."  

أَنَّ رَجُلاً دَخَلَ الْمَسْجِدَ فَصَلَّى وَرَسُولُ اللَّهِ ﷺ فِي نَاحِيَةٍ وَسَاقَا الْحَدِيثَ بِمِثْلِ هَذِهِ الْقِصَّةِ وَزَادَا فِيهِ إِذَا قُمْتَ إِلَى الصَّلاَةِ فَأَسْبِغِ الْوُضُوءَ ثُمَّ اسْتَقْبِلِ الْقِبْلَةَ فَكَبِّرْ
