The sign of a beautiful person is that they always see beauty in others.
If you complain that Allah is testing you too much, you're failing the test.
If you're not doing it for Allah, then don't expect any help from Allah.
Talk to Allah in your own language with your heart fully present. Allah doesn't need you to rhyme or speak arabic.
Positive thinking isn't ignoring life's problems, it's understanding that Allah can make a way out for you if you sincerely try.
When people wear you out, spend some time in isolation with Allah and your relationship with Him will improve as well as with the people.
