Musannaf Ibn Abi Shaybah 31334 — The greatest name of Allah

Abd al-Rahman bin Sabit said that someone supplicated in the time of the Prophet (peace and blessings be upon him), saying: "O Allah, I ask You by means of Your name Allah, that there is no god but You, the Most Gracious, the Most Merciful, the Creator of the heavens and the earth without any model, and when You intend to do something You say to it: Be, and it is." At this the Prophet (peace and blessings be upon him) said: "You, or he, very nearly supplicated by means of the Greatest Name of Allah, the Name of majesty."
