It is narrated from Sayyiduna Sahl bin Sa'd (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The person of the lowest rank in Paradise, though there will be no one lowly there, will be the one who makes wishes, saying with a clear, fluent tongue and a composed mind: Give me this, give me that, until, when he can think of nothing more to ask for, he will be prompted; it will be said to him: Say this, say this. Then it will be said to him: All of that is yours, and as much again besides."
