Reflecting on Our Eternal Returns

Assalamu alaikum, everyone. Lately, I've been pondering how everything in this dunya is temporary, and the only things we'll take with us into the hereafter are our deeds-the good and the bad we've accumulated. It really got me thinking about niyyah (intention), too. Like, if I earn money in a halal way, maybe through an Islamic business or something, and I use that money for halal purposes, will I still earn reward for it in the akhirah? Sometimes it feels confusing whether the intention for the money itself affects the spiritual reward. What are your thoughts?
