And God will watch your actions, and so will the Messenger; then you will be returned to the Knower of the Invisible and the Visible, and He will inform you of what you used to do.”
9:105Say, “Work. God will see your work, and so will His Messenger, and the believers. Then you will be returned to the Knower of secrets and declarations, and He will inform you of what you used to do.”

Those who spend their wealth by night and day, privately and publicly, will receive their reward from their Lord. They have nothing to fear, nor shall they grieve.
