Is someone who slept through the Fajr prayer and did not wake up until after sunrise considered to have delayed the prayer, even though he set an alarm to wake up but was overcome by sleep?

Performing prayer on time is one of the most beloved deeds to Allah. Allah Almighty has indeed ordained it upon Muslims at specific times. Whoever takes the means to wake up, such as setting an alarm, but then turns it off while asleep, incurs no sin. For the sleeper is relieved of responsibility until he wakes up, and there is no negligence in sleep.
