He hears every breath you take, so never - for the blinking of an eye - think He doesn’t hear every Duaa you make. He is As-Sami, the All-Hearing. And He is Al-Mujib, the Answerer. He hears the caller and He responds to the call. Just trust Him.
The best lesson you can teach your soul is to be patient when you’re happy - because happiness ends & to be patient when you’re sad - because sadness ends. Nothing is constant. Everything is temporary. Except Allaah, your Creator. As His creation whom He knows best, be patient during all circumstances, all events, all times. Whatever it is you’re going through, He knows you to put you through it - you. Not someone else; you. So look for the lessons in all circumstances, look for the meaning, look for the blessings. & keep this in mind: all lessons are blessings & all blessings are lessons.
I admire those people who go through tests after tests after tests and still have so much tawakkul in Allah. And subhanallah, it just shows that their tests were infact blessings in disguise for them. Because of their patience and gratitude, Allah increased their Imaan. And what better gift is there than Imaan?
