Abu Dawud Book 2, Hadith Number 1475.

Chapter : Supplications.

Narated By Sa’d ibn Abu Waqqas : Ibn Sa’d said: My father (Sa’d ibn Abu Waqqas) heard me say: O Allah, I ask Thee for Paradise, its blessings, its pleasure and such-and-such, and such-and-such; I seek refuge in Thee from Hell, from its chains, from its collars, and from such-and-such, and from such-and-such. He said: I heard the Apostle of Allah (PBUH) say: There will be people who will exaggerate in supplication. You should not be one of them. If you are granted Paradise, you will be granted all what is good therein; if you are protected from Hell, you will be protected from what is evil therein.
