عَنْ أَبِي هُرَيْرَةَ عَنْ أُبَيِّ بْنِ كَعْبٍ رَضِيَ اللَّهُ عَنْهُمَا قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ مَا أَنْزَلَ اللَّهُ فِي التَّوْرَاةِ وَلَا فِي الْإِنْجِيلِ مِثْلَ أُمِّ الْقُرْآنِ وَهِيَ السَّبْعُ الْمَثَانِي وَهِيَ مَقْسُومَةٌ بَيْنِي وَبَيْنَ عَبْدِي وَلِعَبْدِي مَا سَأَلَ
Sayyiduna Ubayy bin Ka'b (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) said: Allah Almighty has not revealed any Surah like Surah Al-Fatihah in the Torah nor in the Gospel. These are the seven oft-repeated verses, and this Surah is divided between Me (Allah) and My servant, and for My servant is whatever he asks.
