“I often complained about my eyes and once I mentioned it to Abu ‘Abdillah (a.s.) and he said, ‘Should I teach you a supplication that will be for the good of your worldly life and hereafter and a cure for your eye?’ I said, ‘Yes, please do so.’ The Imam said after Maghrib (sunset) prayer say, ‘O Lord, I plead before You through the rights of Muhammad and the family of Muhammad (a.s.) with You to give light to my eyes, understanding in my religion, certainty in my heart, sincerity in my deeds, safety to my soul, increase in my sustenance and gratefulness to You as long as You will keep me (living).”’
