السلام عليكم ورحمة اللّٰه وبركاته If someone wakes up for fajr but decided to stay in bed for 10 min and then go pray fajr. However, he ended up falling asleep and missing fajr. Is he a hypocrite or is this kufr?

Ustadh AbdulAziz al-Haqqan

No, but becareful and serious about waking up for the salah.
