Layth, Ayman, Wakas, Nadia, Farida, Huruf, Noon, Saima and all the oldies, Salam D it's been a long time.
Peace Ayman,
b) the fast of summer creates hardship (contrary to what God tells us) as people who would work in the open would suffer;
c) the summer solstice has the longest day of the year (northern hemisphere) which would take the fast to extreme hours in some habitable regions.
Regards,
Brother layth, my opinion regarding your above assertions, are
2-184........ But fasting is the best for you, if you only knew.
Fasting is for us, probably good for our body health, most likely some cycle gets triggered by a certain duration of deprivation, and that duration has to be long enough to bring in a certain hardship. If we look at the starting and ending markers for fast , it becomes obvious that the earliest possible marker was chosen and described in detail for starting fast.
2-187....You may eat and drink until the white thread of light becomes distinguishable from the dark thread of night at dawn.
and then the period was stretched to the Max by using the last possible Visible Marker, LAYAL, ,
Selection of above markers over (the easier and more obvious) sunrise to sunset is deliberate, probably to stretch the duration of fast to the Maximum.
The winter fast theory which makes fasting easy, in a day of the shortest duration, does not fall in line with the spirit of the most likely intentions of the designer. On the other hand, it dovetails smoothly with the longest days after summer solstice
Yet another indicator, is the command/compulsion, in 2-185.... Those of you who witness this (Full Red moon of the Heat) shahar... ,
Above ensures that, one will Fast only when this full red moon is available in one's geographical location. This is meant to preclude the possibility of a coordinated fast in Northern and southern hemispheres. People above equator fast in summers around longest possible hot days, and people down under would end up fasting in their summers on longest days 6 months later/earlier.
Peace
