There’s a website where you just type in your emotions and current feeling (e.g Angry, Anxious, Confused, Excited etc.) and it gives you an Ayat or Surah that correlates with it.
It is so beautiful and very essential for all those with certain problems.
www.sujood.co, lets you bookmark their website for daily visit and get a related Ayat for your feelings. Signing up is free, you can add favourite Ayat to My Favourite section.
A Mobile app will be very handy and one hopes they come up with it too.
