Bhai jan, if we started fasting for 12 hours, we’d be having iftar at Zurh time. o_O We’re supposed to fast till sunset because Allah said so. That pretty much ends the discussion unless you’re all for amending the Quran and making up your own rules. I mean why don’t we pray Isha in the afternoon then to save us the hassle every night cuz we be like sleepy n stuff.
