Shaykh Hussain Abdul Sattars talks are very very beneficial. I will try to listen to this one, and other related ones, and implement the advices.
I wasnt very clear, but i was referring to the times of the day to sleep and not the way to sleep. I usually work from 16.00 to 23.30, but sometimes in the day time. I have class aswell, but usually just a couple of times a week. I find it very difficult to sleep from (best case scenario) like 00.30 to ~4.00 (fajr right now) and then stay up to try to benifit from the blessed time. For example: every advice concerning memorization of the Quran mentions the time after fajr. But if i just sleep a couple of hours im usually not at all fit to memorize Quran. But on the other hand, if you go to sleep after fajr, the sleep you get is not very beneficial.. which i ofcourse feel aswell. And soon fajr will not enter at all in Sweden, and the timetable i follow sets it at 1.15 (other ones at 00.45). Its very tricky to plan your life according to the sunnah when everything around you follows another clock.
Now it seems like im just nagging away.. But i want to build a solid foundation, and im quite weak and need quite alot of quality sleep to function well. And the mashaikh of this age seems to advice us to be moderate in the jihad against the nafs (see for example the Path to Perfection where the Shaykh mentions that we shouldnt sleep less than 6-7 hours).
