﴿ بِسْمِ ٱللَّهِ ٱلرَّحْمَٰنِ ٱلرَّحِيمِ الٓر ۚ تِلْكَ ءَايَٰتُ ٱلْكِتَٰبِ ٱلْمُبِينِ ﴾

“Alif. Lam. Ra. THESE ARE MESSAGES of a revelation clear in itself and clearly showing the truth:”

Alif lām rā’ God knows best what He means by these letters. Those verses are the verses of the Book the Qur’ān the genitive annexation carries the meaning of partitive min ‘from’ that makes plain the one that manifests truth distinguishing it from what is falsehood.
