I always complained about my eyes. Once I complained about it to Abu Abdillah, peace be upon him, he said: "May I teach you a prayer, beneficial for your life here and hereafter? And which will also treat the pain in your eye?" I said: "Yes." He said: Say after morning and maghrib prayers: "O Allah, I beseech You in the name of Muhammad and his progeny, to bless Muhammad and his progeny, and to bestow light upon my eyes and insight upon my faith, certitude upon my heart, sincerity upon my acts, security upon my self, abundance upon my subsistence; and grant me to be ever thankful to You as long as You keep me." And may Allah bless our master Muhammad and his progeny.
