Named for its opening two letters, this chapter carries the prophetic honorific "The Heart of the Quran." Occasionally called Sūrat Ḥabīb al-Najjār after the believer who came running from the farthest part of the city, these 83 Makkan verses arrived 41st in the order of revelation. They descended between Sūrat al-Jinn and al-Furqān to console the Prophet during severe early persecution.

The text opens by establishing the divine origin of the message, then shifts to a parable of a city that rejected its messengers. From this historical warning, the focus expands to the cosmos, presenting the universe's signs as proof of the Resurrection. The narrative then accelerates toward the trumpet blast, detailing the sudden arrival of the Hour and the separation of believers and disbelievers.

The closing argument anchors itself in the origins of mankind, using the effortless initial creation of humanity to prove the ease of raising the dead. The text ultimately lands on a final affirmation of monotheism and absolute sovereignty, returning control of all existence to Allah.
