'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.'"

'O Allah, make me healthy in my body. O Allah, make me healthy in my hearing. O Allah, make me healthy in my sight. There is no god but You.' You repeat it three times in the evening and three times in the morning. And you say, 'O Allah, I seek refuge with You from disbelief and poverty. O Allah, I seek refuge with You from the punishment of the grave. There is no god but You,' and you repeat it three times in the evening and three times in the morning." He replied, :Yes, my son. I heard the Messenger of Allah, may Allah bless him and grant him peace, say them and I like to follow his sunnah."

The Messenger of Allah ﷺ mentioned the Dajjal (Antichrist) saying, “If he comes forth while I am among you I shall be the one who will dispute with him on your behalf, but if he comes forth when I am not among you, a man must dispute on his own behalf, and Allah will take my place in looking after every Muslim. Those of you who live up to his time should recite over him the opening verses of Sūrah al-Kahf, for they are your protection from his trial.” We asked, “How long will he remain on the earth?” He replied, “Forty days, one like a year, one like a month, one like a week, and rest of his days like yours.” We asked, “Messenger of Allah ﷺ, will one day’s prayer suffice us in this day which will be like a year?” He replied, “No, you must make an estimate of its extent. Then Jesus son of Mary will descend at the white minaret to the east of Damascus. He will then catch him up at the gate of Ludd and kill him.” Reference: Sunan ad-Darimi 4321; A more detailed narration is found in Sahih Muslim 2937
