Rdminder#1: Everyone will Die

Asalam o Alaikum!
I'll be writing explanations of different ayahs as our reminder so that we can make ourselves better before the death comes and then we will have no time to repent. Some of the explanations will also be based on the lectures of Nauman Ali Khan.
So just read them even if you are too lazy to do it. The expalnations won't be too long.
May Allah make us His obedient servants.
