البلاغ
al-Balāgh
A name of the Quran: that which has reached humankind from God.
What it means
Al-balāgh comes from the root meaning to arrive or to reach. As a name of the Quran, Faruqi explains, it refers to the message that has reached human beings from God. The word stresses that the Quran is a message delivered to its recipients, and the word is also tied to the task of the Messenger, which is to convey it. The Quran uses the word of itself: it says “this is a message (balāgh) for mankind” (14:52). It also describes the duty of the Messenger as plain delivery (5:99). The name therefore joins the content of revelation with the duty of conveying it, which Muslims inherit as a duty to pass the message on.
Often misunderstood as
That it is only a general word for “message”, when it is a name given to the Quran as the message that has reached humankind.
What the sources say
Several verses, among them 5:67 and 5:99, describe the Prophet’s duty as balāgh, conveying what was revealed.
