You have to ignore and fight off these waswas, as the Shaytan wants to trick you so that you stop doing good! Increase doing it to make him more upset and don’t listen to him.

Whenever I am doing good for example Telling someone Hadith or a verse from Quran. All of a sudden Shaitan blows evil thoughts inside my heart that You are doing to draw others attention towards yourself ; you are a hypocrite ; you are doing to make yourself respectable. After all these thoughts I become very much worried & suspicious reagarding my Imaan.
