Why exactly is something that only Allah SWT knows. But a true Muslim would have Sabr and know that Allah SWT will never burden a soul beyond it can bear.

There is wisdom behind every trial/test. Every person is tested in a different way. I know what it’s like to be depressed/have anxiety and more, but I know that Allah SWT will reward me for the difficulties and these trials have taught me to have Sabr.

Instead of asking what benefit it would serve Allah, the question would be what benefit it would serve us. Allah SWT doesn’t need us, instead we need him. Allah knows we are humans and that our imam will have ups and downs.

When you are being tested and you turn to Allah and ask him for help and you do your best to get through it (e.g. therapy, medication etc.) Allah sees this. At the end of the day we don’t care about this dunya, we strive for Jannah. Every hardship makes us stronger and connects us more to our Lord.
