This is a test for you and you have to be patient. If you give up hope, the only one who would become a loser in this situation is you! Allah decreed everything 50,000 years before creating the universe! We don’t know what He had decreed but we know that we are His servants and slaves and that He may do whatever He Wills! Therefore, you have no other alternative but to worship Him, humiliate yourself to Him and hope for the best while being content with whatever He decrees!

Perform ruqyah and never give up as you will be rewarded in sha Allah.

Sir i am suffering from eye problem in my left eye for last 4 years. Doctors said they dont have any treatment for that disease. I was praying to Allah for last 4 years but nothing happened. Now I’m losing hope. What should I do. Is there any cure to this disease called Lazy Eye or Amblyopia in islam. Waiting for your response.
