﴿ وَلَقَدْ ءَاتَيْنَٰكَ سَبْعًۭا مِّنَ ٱلْمَثَانِى وَٱلْقُرْءَانَ ٱلْعَظِيمَ ﴾

“AND, INDEED, We have bestowed upon thee seven of the oft repeated [verses], and [have, thus, laid open before thee] this sublime Qur'an:”

And verily We have given you seven of the oft-repeated verses — the Prophet s said that this meant sūrat al-Fātiha as reported by the two Shaykhs Bukhārī and Muslim since it is repeated in every unit of prayer rak‘a — and the great Qur’ān.
