 Local tradition centered on Ayn al @-@ Hajja , the spring of Lajjun , date back to the 10th century CE when the village was under Islamic rule . According to geographers of that century , as well as the 12th century , the legend was that under the Mosque of Abraham , a " copious stream flowed " which formed immediately after the prophet Abraham struck the stone with his staff . Abraham had entered the town with his flock of sheep on his way towards Egypt , and the people of the village informed him that the village possessed only small quantities of water , thus Abraham should pass on the village to another . According to the legend , Abraham was commanded to strike the rock , resulting in water " bursting out copiously " . From then , the village orchards and crops were well @-@ irrigated and the people satisfied with a surplus of drinking water from the spring .
