I have heard Rasool-Allah -saww say: ‘Allah -azwj Said to me, ‘O Muhammad -saww And We have Given you seven of the oft-repeated (verses) and the Magnificent Quran [15:87] .
Allah -azwj Referred to it separately in the Opening of the Book and Made it special to the Magnificent Quran and this Opening of the Book is from the treasures of the Throne.’ وَ إِنَّ اللَّهَ تَعَالَى خَصَّ بِهَا مُحَمَّداً ص وَ شَرَّفَهُ [بِهَا] وَ لَمْ يُشْرِكْ مَعَهُ فِيهَا أَحَداً مِنْ أَنْبِيَائِهِ مَا خَلَا سُلَيْمَانَ ع فَإِنَّهُ أَعْطَاهُ مِنْهَا «بِسْمِ اللَّهِ الرَّحْمنِ الرَّحِيمِ» أَ لَا تَرَى أَنَّهُ يَحْكِي عَنْ بِلْقِيسَ حِينَ قَالَتْ: «إِنِّي أُلْقِيَ إِلَيَّ كِتابٌ كَرِيمٌ إِنَّهُ مِنْ سُلَيْمانَ وَ إِنَّهُ بِسْمِ اللَّهِ الرَّحْمنِ الرَّحِيمِ» Allah -azwj Bestowed a special Favour on Muhammad -saww with it and did not let anyone else from the Prophets -as have a share in it except for Prophet Sulayman -as as He -azwj Gave him -as بِسْمِ اللَّهِ الرَّحْمنِ الرَّحِيمِ» ( In the Name of Allah the Beneficent, the Merciful [1:1] ) from this.
Do you not see when he -as wrote to Bilquis and she said, She said: O you Chiefs! An honourable letter has been delivered to me [27:29] It is from Sulayman, and it is in the Name of Allah, the Beneficent, the Merciful ?
So, the one who recites this and believes in the Wilayah of Muhammad -saww and his ‑saww Pure Progeny -asws , and believes in their manifest and hidden matters, then Allah -azwj Mighty and Majestic will Give him a Reward for every letter of it, each of which will be better than this world and whatever is in it from the varieties of its wealth and (all of) its goodness.
