ANSWER:

You must keep on fighting this feeling and acknowledge that no human can reward you or benefit you and that only Allah’s pleasure that counts.

I went to a place where no one can see me but mum came on the other side of the door before i started praying to grab clothes of the door. im not sure if she saw me or not but i felt riyaa inside. i didnt have time to look at my intention so i just prayed but i truly felt like i wasnt sincere for the first rakah maybe as i thought she knew i was praying then realised Allahs watching and tried.
