in Edition Clear Qur'an by Talal Itani / Al-Furqaan (The Criterion)

25:26On that Day, true sovereignty will belong to the Merciful, and it will be a difficult Day for the disbelievers.

25:52So do not obey the disbelievers, but strive against them with it, a mighty struggle.

25:55And yet, instead of God, they serve what neither profits them nor harms them. The disbeliever has always turned his back on his Lord.
