2347 In the latitude of Ephesus , 38°north, i.e. well above the sun's northern declination, a cave opening to the north, would never have the heat of the sun within it, as the sunny side would be the south. If the youths lay on their backs with their faces looking to the north, i.e. towards the entrance of the Cave, the sun would rise on their right side, declining to the south, and set on their left sides leaving them cool and comfortable. 2348 The youths, having faith and trust in Allah, found safety and refuge in the Cave. They were protected from the persecution and violence of the heathen. Their prayer (18:16) was heard.
