And We have bestowed upon thee the Seven Oft-repeated (verses) and the Grand Qur’an.
That Surah Al-Fatihah (The Opening) has been called the Glorious
Quran in this verse (87) indicates that Surah Al-Fatihah is, in a way, the
whole Quran – because the basic principles of Islam have been merged
In order to understand this, one must keep in mind that the words: (the seven oft-repeated verses and the glorious Qur’an) in verse (87) are interpreted by the commentators in different ways. Most of them are of the view that
‘seven oft-repeated verses’ refer to Surah al-Fatihah which consists of seven verses.
Since these seven verses are repeated in every salah, they have been referred to in
the verse 87 as ‘oft-repeated verses’. Then, the words ‘and the glorious Qur’an’ occurring after it are of explanatory nature which refer to the same ‘seven oft-repeated
verses’. Therefore, the name of the ‘glorious Qur’an’ has been given here to the
Surah al-Fatihah itself. The comment of the author is based on this interpretation.
Narrated Abu Huraira:
The Prophet (ﷺ) said, “Angels keep on descending from and ascending to the Heaven in turn, some at night and some by daytime, and all of them assemble together at the time of the Fajr and `Asr prayers. Then those who have stayed with you over-night, ascent unto Allah Who asks them, and He knows the answer better than they, “How have you left My slaves?” They reply, “We have left them praying as we found them praying.” If anyone of you says “Amin” (during the Prayer at the end of the recitation of Surat-al-Faitiha), and the angels in Heaven say the same, and the two sayings coincide, all his past sins will be forgiven.”
