The Shaytaan whispers to him that he is showing off so that he will give up doing acts of worship

Shaykh Ibn Uthaymeen (may Allaah have mercy on him) was asked:

When a person thinks of doing a good deed, the Shaytaan comes and whispers to him: “You want to do that to show off and have a good reputation,” so he backs off from doing that good deed. How can we avoid this?

He replied:

That can be avoided by seeking refuge with Allaah from the accursed Shaytaan, and going ahead with the good deed. You should not pay attention to this waswaas (whisper from the Shaytaan) that puts you off doing good. If you turn away from this and seek refuge with Allaah from the accursed Shaytaan, the problem will disappear, by Allaah’s leave.
