"O mankind, there has come to you an admonition from your Lord and healing for what is in the chests(i.e the heart) and guidance and mercy for the believers" (10:57)

Do you have everything in life, yet you're missing something? There's a void within you that you would want to fill it with socialising, books, sleep, etc.I'm not telling these are bad... Everyone needs sleep... And the other two of course. Yet what's mentioned here is the excess, you keep doing only one... Or even all three all the time so that there's no emptiness in your heart? So that the void within you would get filled. It's like you finish one book, then go to another then another then another.... Just a repeatedly endless cycle to find yourself happy and content...

Honestly, this was what I used to do too.... After school was over this was what we all craved for😍 and that's exactly what I was doing, but I felt empty inside, at first it had its perks but then obviously it faded, and every time I kept doing something like that I'll keep asking myself, why am I doing this? It felt pointless, because I wasn't living for anything, I felt useless just being there... That's when I received the best thing ever.

Every manufacturer knows their product inside out, wouldn't you agree? At the same time, the one who created our hearts, Allah knows what it craves the most, the Qur'an.

Have you ever felt sad? Depressed? Lost? The healing is in the Qur'an, because Allah says that in it there is healing, guidance and mercy! So you feel depressed? The healing is in the Qur'an. You feel lost? The guidance is in the Qur'an.

The Qur'an is only a healing when you use it properly. It's unique, unlike other things. Eg. For medicine you drink it and you don't know if it'll work or not, but you have it and you could get better. But in the Qur'an, you need to be certain that it would work, only when you have the certainty, it'll work. Same goes for guidance. When you seek for guidance from it, only then will guidance reach you, but if you approach it with doubt or anything else, then you might get something else entirely different, Allah knows best.

There's peace and contentment only in the Qur'an, and Alhamdulillah after fully witnessing it myself, I give you my word, that what you seek in it, you'll get it.

I put my own personal experience so that people can relate to it, had no other intentions:)
And notice that in this verse, all of mankind is addressed! The Qur'an isn't restricted to only the believers:)
