Allah says in an amazing verse in the Quran, and this is the most motivational, the most inspiring verse:
Allah does not charge a soul except [with that within] its capacity. (Quran 2:286)
Allah is speaking to us and informing us that He will never burden a soul with anything more than that which it can carry.
Whatever you're going through no matter how hard, know that Allah knows you can get through it. Allah knows you can pass. And you have to believe this. Otherwise what you're implying indirectly that ‘Allah is unjust and He is burdening me with something I can't handle.’
Allah says, ‘I will never do this to my slave.’
You Can Pass
So, let's create the worst scenario you could ever think of: you came home, you just lost your job, on the way you had a car accident, you smashed your car, by the time you’re home everyone in your family was murdered… Throw the worst scenario you could ever possibly put together…
We all get in such situations, and Allah knows that we can pass and get through it. Because He will never put us in a situation that we cannot handle and get through.
And the Prophet Muhammad (peace be upon him) says in a very amazing hadith:
Amazing is the condition of a believer.
Notice how the Prophet Muhammad doesn't say ‘the condition of a Muslim’. Because to be a Muslim is entry level, anyone can really become a Muslim. But here he's been very specific because being a believer is a higher level. He says:
"Amazing is the condition of a believer. Whatever happens to him or her is good."
What does that mean? Whatever happens to you and I is good; when something good happens the Prophet (peace be upon him) says you praise Allah and you thank Him and this is good for you. And when something bad comes your way or a test or a trial or a tribulation… then you are patient and you turn back to Allah, and this is also good for you.
For the case of a believer anything and everything that happens in his or her life it's all good; there is no bad.
Why? Because ultimately where did that come from?
We must understand that He the one who's in control. He knows what is best for us and we must trust in Him.
