The Quran is the literal word of Allah, revealed to Muhammad ﷺ through Jibril in Arabic, recited in worship, and transmitted to us in unbroken chains, letter by letter.
Allah challenged mankind to produce even one surah like it — and none could. Its language, guidance and preservation remain a living miracle in our hands today.
The Quran calls itself guidance (hudan), light (nur), a healing (shifa) and a criterion (furqan). Reading one letter earns ten rewards — and it will intercede for its companions on the Last Day.
