Why does Allāh want us to be patient in times of trial and problems

Why does Allāh want us to be patient in times of trial and problems? It's because Allāh wants us to realize that everything will be better. Allāh wants us to realize that He is just testing us, and His trial is not a hindrance to us, rather it is a blessing. How beautiful would it be if every trial that Allāh gave us—we deal with it as what Allāh has commanded us to do,—with patience. Every moment that we deal with problems with beautiful patience is an act of worship. An act of worship that will surely be greatly rewarded in the hereafter. 

As Allāh promised us in the Qur'an, 

إِنَّمَا يُوَفَّى الصَّابِرُونَ أَجْرَهُمْ بِغَيْرِ حِسَابٍ

"Indeed, the patient will be given their reward with account."

إِنَّ مَعَ الْعُسْرِ يُسْرًا 

"Verily, with every hardship comes ease."

May Allāh keep us steadfast in His deen.
