Hazrat Ali (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: The supplication most frequently made by me and all the prophets before me at the place of Arafah is this: There is no deity except Allah, He is alone, He has no partner, His is the dominion and to Him belongs all praise, and He has power over all things. O Allah! Place light in my heart, and place light in my ears, and place light in my eyes. O Allah! Open my chest for me, and make my affair easy for me, and I seek refuge in You from the whispers of Satan, from the corruption of my affairs, and from the trial of the grave. O Allah! I seek refuge in You from the evil of everything that enters the night and from the evil of everything that enters the day, and from the evil of that which the winds bring.
