On this page you can get a detailed analysis of a word or phrase, produced by the best artificial intelligence technology to date:
The mysterious letters (muqaṭṭaʿāt, Arabic: حُرُوف مُقَطَّعَات ḥurūf muqaṭṭaʿāt, "disjoined letters" or "disconnected letters") are combinations of between one and five Arabic letters figuring at the beginning of 29 out of the 114 chapters (surahs) of the Quran just after the Bismillāh Islamic phrase. The letters are also known as fawātiḥ (فَوَاتِح) or "openers" as they form the opening verse of their respective surahs.
Four chapters are named for their muqaṭṭaʿāt: Ṭā-Hā, Yā-Sīn, Ṣād and Qāf.
The original significance of the letters is unknown. Tafsir (exegesis) has interpreted them as abbreviations for either names or qualities of God or for the names or content of the respective surahs. The general belief of most Muslims is that their meaning is only known to Allah.
