Morning
We have reached the morning and at this very time all sovereignty belongs to Allah, Lord of the worlds. O Allah, I ask You for the good of this day, its triumphs and its victories, its light and its blessings and its guidance, and I take refuge in You from the evil of this day and the evil that follows it.
