What credit for him who mediates good for himself?

Whoever brings good, he shall have ten times what he brought. And whoever brings evil, he shall be punished only with its equivalent, and they shall not be wronged.
Prophet Hud/11:114
Observe the prayer at both ends of the day and the close part of the night. The good deeds wipe away the evil deeds. This is an admonition for those who will take admonition.
The Cow/2:271
How good it would be if you revealed your charity. But it is better if you hide them and give them to the needy, and that will cover some of your sins. Allah is aware of what you do.
