If one delays the witr and sleeps through it, is it obligatory for him to make it up?

The questioner : Yes, a man says that the witr prayer was missed on the grounds that he intended to delay it in order to, meaning, stand in night prayer, and then conclude with it, otherwise the dawn would catch him. Is it obligatory for him to make it up?

The Shaykh : Was he intending to pray the witr?

The questioner : The witr; he intended to delay it.

The Shaykh : Listen, answer the question yourself, may Allah guide you.

The questioner : What is the question?

The Shaykh : Ah, you want to speak but you don't know the question. Was he intending to stand up in the last part of the night to pray the witr?

The questioner : Yes.

The Shaykh : And then he was unable to get up. Or was he able to get up?

The questioner : He was unable to.

The questioner : Yes.

The Shaykh : He was unable to, so when he wakes up, he prays.

The questioner : The witr?

The Shaykh : The witr.

The questioner : And then the Fajr.

The Shaykh : Yes, exactly.
