Taking A Short Nap After Waking Up For Fajar
If one has a genuine difficulty in waking up, or if one had the intention of waking up but slept through it then they can offer fajr as soon as possible after waking up; the prayer becomes due as soon as one wakes up. This doesn’t mean that we should be careless about it.
