Al-Adab Al-Mufrad #698

'Abdullah ibn 'Abbas said, "When the Prophet, may Allah bless him and grant him peace, prayed the night prayer, and finished his prayer, glorifying Allah as he deserves, he said at the end of it, 'O Allah, give me a light in my heart and give me a light in my hearing and give me a light in my sight. Give me a light on my right and a light on my left and give me a light in front of me and a light behind me and increase me in light. Increase me in light, and increase me in light.'"
