When you go without eating, don't try to look gloomy as those show-offs do when they go without eating. I can assure you that they already have their reward.
When you give to the poor, don't blow a loud horn. That's what show-offs do in the meeting places and on the street corners, because they are always looking for praise. I can assure you that they already have their reward.
When you pray, don't be like those show-offs who love to stand up and pray in the meeting places and on the street corners. They do this just to look good. I can assure you that they already have their reward.
Warn the rich people of this world not to be proud or to trust in wealth that is easily lost. Tell them to have faith in God, who is rich and blesses us with everything we need to enjoy life.
