A Medinan sura that takes its title from the thunder that praises God in verse 13. The sura is distinguished by its moving description of God’s power and knowledge. Muhammad’s place in a long tradition of prophets, none of whom could produce miracles on request, is stressed, and his role emphasized: it is only to deliver the message. God is the One who will call people to account for their deeds, and He is the witness for the truth of the message.
