Today is Friday, juz came back from class, really tired. need a short rest, then will go to the nearest mosque for Solat Jumaat. It is a sunnah to have a short nap before 'zohor' time, the thing that Rasulullah always did in his life. It is also an energy recovery, to re-energize energy that we used in the morning, and to prepare for the evening. So, happy napping guys.
p/s: nap is not sleep. you sleep, you might not go to perform Solat Jumaat at all. You nap, you will have enough energy to do it. And of course, preventing you from fall asleep during the sermon before the solat. Practice Sunnah =)
