حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، أَخْبَرَنَا مَالِكٌ، عَنْ سُمَىٍّ، عَنْ أَبِي صَالِحٍ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ إِذَا قَالَ الإِمَامُ ‏[quran sura="1" aya_start="7" aya_end="7"]{‏غَيْرِ الْمَغْضُوبِ عَلَيْهِمْ وَلاَ الضَّالِّينَ‏}‏ فَقُولُوا آمِينَ‏.‏ فَمَنْ وَافَقَ قَوْلُهُ قَوْلَ الْمَلاَئِكَةِ غُفِرَ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ ‏"‏‏.‏

باب ‏<a href="https://quran.com/1/7-7">{‏غَيْرِ الْمَغْضُوبِ عَلَيْهِمْ وَلاَ الضَّالِّينَ‏}</a>‏

Narrated Abu Huraira:

Allah's Messenger (ﷺ) said, "When the Imam says: 'Ghair-il-Maghdubi `alaihim Walad-Dallin (i.e. not the 
path of those who earn Your Anger, nor the path of those who went astray (1.7)), then you must say, 
'Ameen', for if one's utterance of 'Ameen' coincides with that of the angels, then his past sins will be 
forgiven."

"...Not (the way) of those who earned Your Anger, nor of those who went astray." (V.1:7)

Sahih al-Bukhari

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ، عَنْ مَالِكٍ، عَنْ سُمَىٍّ، مَوْلَى أَبِي بَكْرٍ عَنْ أَبِي صَالِحٍ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ إِذَا قَالَ الإِمَامُ ‏[quran sura="1" aya_start="7" aya_end="7"]{‏غَيْرِ الْمَغْضُوبِ عَلَيْهِمْ وَلاَ الضَّالِّينَ‏}‏ فَقُولُوا آمِينَ‏.‏ فَإِنَّهُ مَنْ وَافَقَ قَوْلُهُ قَوْلَ الْمَلاَئِكَةِ غُفِرَ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ ‏"‏‏.‏ تَابَعَهُ مُحَمَّدُ بْنُ عَمْرٍو عَنْ أَبِي سَلَمَةَ عَنْ أَبِي هُرَيْرَةَ عَنِ النَّبِيِّ صلى الله عليه وسلم وَنُعَيْمٌ الْمُجْمِرُ عَنْ أَبِي هُرَيْرَةَ رضى الله عنه‏.‏

باب جَهْرِ الْمَأْمُومِ بِالتَّأْمِينِ

Narrated Abu Huraira:

Allah's Messenger (ﷺ) said, "Say Amen when the Imam says 'Ghairi l-maghdubi `alaihim wala d-daalleen' 
(not the path of those who earn Your Anger (such as Jews) nor of those who go astray (such as 
Christians)); all the past sins of the person whose saying (of Amin) coincides with that of the angels, 
will be forgiven".

Saying of Amin aloud by the followers

باب وُجُوبِ قِرَاءَةِ الْفَاتِحَةِ فِي كُلِّ رَكْعَةٍ وَإِنَّهُ إِذَا لَمْ يُحْسِنِ الْفَاتِحَةَ وَلاَ أَمْكَنَهُ تَعَلُّمُهَا قَرَأَ مَا تَيَسَّرَ لَهُ مِنْ غَيْرِهَا

Abu Huraira reported: The Messenger 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.

It Is Obligatory To Recite Al-Fatihah In Every Rak'ah; If A Person Cannot Recite Al-Fatihah Or Cannot Learn It, Then He Should Recite Whatever Else He Can Manage
