It’s really a big issue to accept, simply accept means that you are happy, but for sure it doesn’t mean that you don’t care. There is a big difference between you accept being happy, and on the other hand you don’t care any more.
For example if you are 40’s doesn’t have money you still can think how to enjoy taking your wife and walking, sharing some jokes and take street food instead of make a reservation in an expensive restaurant.
Weight your happiness this will reflect your acceptance
Your Acceptance for sure is reflecting your believe, your believe in Allah as a god, your believe in yourself and your abilities as a human.
Your believe in Allah means how you trust Allah,
- how you trust he tested you for a reason
- how he will get you out of this situation
- how he is always there listening to your doaa
Your believe in yourself and your humanity means that you know yourself, you accept that as a human you are not perfect so you did mistakes and you will take these mistakes as a lesson learned to improve yourself and build a better version of you.
Acceptance (Reda) is the most important in life
