This is one of the earlier Meccan Sūras, chronologically cognate with S. 91. The subject-matter is the persecution of God’s votaries. God watches over His own, and will deal with the enemies of Truth as He deals with them in the past.
[85:1-22] Woe to those who persecute Truth! They are being watched by mighty Eyes; they will have to answer when the Judgment comes; and a clear Record will witness against them. Are they cruel to men because of their Faith? The Fire they use will be turned against them. For God is strong, and will subdue the mightiest foes. Be warned, and learn from His gracious Message, preserved through all Time!
