( الر…) (Alif, Lam, Ra…): This Surah start with the ‘discrete letters’, which we have previously shed light on during the interpretation of Surah Al-Baqarah.

(… تِلْكَ آيَاتُ الْكِتَابِ…) (… These are the verses of the clear Book…):  The verses mean the “signs,” Allah says:

 قَالَ إِن كُنتَ جِئْتَ بِآيَةٍ فَأْتِ بِهَا إِن كُنتَ مِنَ الصَّادِقِينَ

( [Pharaoh] said, “If you have come with a sign, then bring it forth, if you should be of the truthful.”) (Al-A’raaf: 106)

They asked for a miracle.

When Allah (swt) mentions the word ‘book’, we should understand that it refers to the Holy Quran.

(... الْمُبِينِ ) (…  the clear):   Means it clarifies everything that human movement needs on Earth, Allah (swt) says:

 مَّا فَرَّطْنَا فِي الْكِتَابِ مِن شَيْءٍ

( We have not neglected in the Register a thing.) (Al-An’aam: 38)
