The visit of Prophet Abraham and Isaac and Abraham's prediction and desire to buy the Valley of Peace.
Those who have visited Najaf will remember vividly that to the north and east of the town there are acres of graves and myriads of domes of various colours and at various stages of disrepair. Whoever goes to Najaf will follow a road that approaches the town by a winding course through this vast cemetery. The Prophet Abraham had come to this place along with Isaac; there had been many earthquakes in the vicinity, but while Abraham remained there, there were no tremors. On the night, however, when Abraham and Isaac went to a different village, and sure enough Najaf was visited with another earthquake.
