Assalamu alaikum ustadh. If a person sleeps around 20 mins before fajr starts, having a doubt if they'll wake up. But yet they set the alarm and slept. Not sure if Alarm rang or phone got switched off before that. They missed Salah. Can sleep be used as an excuse in this case? Jazakallahu Khairan

Ustadh AbdulAziz al-Haqqan

Of u r up that late dont sleep pray then sleep. Also sleep early so that u can get up for the salah. This is your top priority.
