It is narrated from Abu Harith Kermani, may Allah have mercy on him, that I heard a man say to Abu Raja: I greet you with peace and ask Allah Almighty to gather me and you in the abode of His mercy. Abu Raja said: Do you have any power over this? And he said: Do you know what the abode of mercy is? He said: Paradise! Abu Raja said: Your answer is wrong. He asked: Then what is the abode of mercy? Abu Raja said: The abode of mercy means the Lord of all the worlds.
