صَحِيحُ مُسْلِمٍ
Sahih Muslim 396 a
The Book of Prayers
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
حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ، حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ حَبِيبِ بْنِ الشَّهِيدِ، قَالَ سَمِعْتُ عَطَاءً، يُحَدِّثُ عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ لاَ صَلاَةَ إِلاَّ بِقِرَاءَةٍ . قَالَ أَبُو هُرَيْرَةَ فَمَا أَعْلَنَ رَسُولُ اللَّهِ صلى الله عليه وسلم أَعْلَنَّاهُ لَكُمْ وَمَا أَخْفَاهُ أَخْفَيْنَاهُ لَكُمْ .
Abu Huraira reported: 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 Prophet).
