This sūra opens by extolling the glory of God, and then appeals for belief in and support of the Prophet and his cause. It describes the different fates awaiting the ‘hypocrites’ and believers, and concludes with a reference to the previous messengers Abraham, Noah, and Jesus. Q57 receives its title from the mention of ‘iron,’ which God has sent down along with ‘the Book’ and ‘the scale’ (Q57.25).
