Don't ever put your hopes and expectations on anyone, no matter how close that person is to you.
If you do, then sooner or later, you will definitely be forced to regret.
Because, after all, a human is a human, and a human can only go so far, and do so much. Our capabalities are extremely limited.
Unfortunately today, we love to magnify our abilities to the maximum, pretending to be what we aren't, bragging that we can do what we can't.
So then what do we do? We depend for everything on such people, erroneously imagining that they can do alot for us.
It isn't too long after that that reality hits us hard, towing along with it alot of sadness, heart pain, and regret.
Why put ourselves through this suffering in the first place??
Why don't we place all our hopes on The only Being Who is Limitless, who can fulfill our every expectation, who will never give us any grief in return??
Indeed, only those are successful and lead happy, satisfied lives who put all their hopes and expectations on Allah Ta'ala.
