ARABIC VERSION: 3D-Surface Modeling for fajr verification in Medina


This video demonstrates the use of a gadget camera to record fajr in Medina. At the same time, it shows that the global twilight pattern can be developed through a crowdsourcing collaboration scheme. Furthermore, the 3D-Surface Modeling technique can be used to verify the birth of the fajr which occurs when the sun was at its depression angle of -10.4 degrees, not -18.5 degrees as officially stipulated. Saudi Arabia's ulemas have been correct in putting the delay about 30 minutes from the fajr call recitation to the iqamah. Otherwise, the true fajr hasn't been born when Muslims perform the fajr prayer.
