This sūrah, which consists of 83 verses, was revealed in the mid-Makkan period. It takes its name from the first verse, the shortest in the Qur’ān, and which, according to some, implicitly means a human being. It deals, using diverse arguments, with three of the pillars of faith, namely the Divine Oneness, afterlife, and Prophethood. God’s Messenger, upon him be peace and blessings, declared that this sūrah is the heart of the Qur’ān (at-Tirmidhī, “Thawāb al-Qur’ān,” 7) because it stirs up “dead” hearts to awaken them to life. He also advised its recitation over one who is at one’s death-bed.
