"Be mindful of Allah, you will find Him before you.
Get to know Allah in prosperity and He will know you in adversity.
Know that what has passed you by was not going to befall you;
and that what has befallen you was not going to pass you by.
And know that victory comes with patience,
relief with affliction,
and ease with hardship."
(Bukhari)
Golden words to live by. The keys to success, happiness, and patience are all right here. Of course they are found in Islam, of course. This religion is more than just a religion, it is a deen, a way of life.
We have an entire way of life laid out for us, an easy one that give us freedom from the evil in this world. And if we follow it, insha'Allah, Jannah will be our final abode.
