My old macalin told me you get ajar for every letter of the quran you readdid you just call learning about your deen and memorizing Quran a waste of time?
you get ajar no matter what even if you do not understand the Arabic language. Your scales still grow. Imagine how heavy it is from your entire childhood weekends of recitation added to your scale for the last day.
That’s the best use of time. That’s investment for your hereafter.
