Does one sin if he sleeps through the Fajr prayer?

Question:
May Allah reward you, Your Eminence, father. The questioner says: I live in a university dormitory. I set my alarm for the time of the Fajr prayer, but sometimes I do not wake up until after the sun has risen. Is there any sin on me for that?

Answer:
You dealt with the cause, but sleep overcame you. You are excused in this. Sleep overcame you, and you intended to get up and took the measure to wake up, but sleep overcame you. You are excused in this. Yes.
