It was narrated that Ubayy bin Ka’b said, “The Messenger of Allah ﷺ said, Allah did not reveal in the Tawrāh or the Injīl anything like Umm al-Quran (al-Fātiḥah), which is the seven oft-recited (verses), and (Allah said) it is divided between Myself and My slave will have what he asked for.” Reference:

Jami` at-Tirmidhi 3125

عَنْ أُبَىِّ بْنِ كَعْبٍ، قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم ‏

‏ مَا أَنْزَلَ اللَّهُ فِي التَّوْرَاةِ وَلاَ فِي الإِنْجِيلِ مِثْلَ أُمِّ الْقُرْآنِ وَهِيَ السَّبْعُ الْمَثَانِي وَهِيَ مَقْسُومَةٌ بَيْنِي وَبَيْنَ عَبْدِي وَلِعَبْدِي مَا سَأَلَ
