if you know yourself, you'll be shown your wealth

"Everything isn't a predictable occurrence
If you've experienced everything except a purpose
Then you've missed everything that was meant to be caught
Life sessions aren't lessons that can be simply taught
You gotta feel the matter, build the data
You gotta strengthen self or your shield will shatter

I've fallen down but I got up friend
Fell twice
Three times
Got up again and again
And again, it's nobodies but my own it didn't end
You only don't win when you give in

Exercise knowledge to increase your wealth
If you know yourself you'll be shown your wealth"

In Islam we are forbidden to lose hope: "Certainly no one despairs of Allah's Mercy, except the people who disbelieve." (12.87)

We are going to be tried and tested often, but it's for our own benefit; to enter Jannah iA. Use these times of trial to get to know yourself and strengthen your character + iman (aka your shield). Don't expect to go through life like it's a breeze, it hasn't been for anyone:

"Or think you that you will enter Paradise while yet there has not come to you the like of that which came to those who died before you? Affliction and adversity befell them; they were shaken as with earthquake, till the Messenger (of Allah) and those who believe along with him said: 'When will Allah's help come?' Now surely Allah's help is near." (2.214)

But yeah, now that we are equipped with this knowledge, we should be thankful for what Allah (swt) has given us and when times get rough - make dua & power through it:

"And whatever of blessings and good thing you have, it is from Allah. Then, when harm touches you, unto Him you cry aloud for help." (16.53)

Dua rarely goes unanswered, and on the rare occasion that it does, it happens for a reason as He is All-Wise and All-Knowledgeable. There are two possibilities:

1. Either Allah delays it for the appropriate time,

2. Or He may may not give it because it may not be good for us - BUT He may give us something better than that or reward us in the Hereafter.
