Introduction
The Quran contains 114 suras, of which 29 are prefixed with initials. In eight of the occurrences of these initials, it follows with some variation of the statement “til’ka āyātu l-kitāb” ( تِلْكَ ءَايَـٰتُ ٱلْكِتَـٰب) which translates to “this is proofs of the book.” Some misunderstand this verse and think that “ayat” means verses, which is the word’s common use today, but Quranically, the word ayat almost always refers to a sign or miracle rather than verses.
