When we say that angels wake you up for Fajr, does the person feel their presence, hears a loud sound, and sees their light before waking up? How do people describe such a blessing or is it just a waking up with nothing being witnessed right before?
We as fallible humans can not see the angles nor hear their voice nor feel their light in this world. Pious believers will the angles after this life as we read in Quran (On that Day, they will see the angles) Sura Al-Forqan, verse 22.
Wassalam.
