Rasulullah (Salallahu alayhi wasallam) used to say that in Tahajjud I think... I remember Sheikh Shuraim used the " You are the Truth; Your promise is True, Your word is the Truth, the meeting with You is True, Paradise is true, Hell is true, the Hour is true" part in one of his Ramadan duas...
Anyways..
Our Lord! Pour out on us patience and constancy, and make us die as those who have surrendered themselves unto You.
