When Imam Ali, marching at the head of his army towards Syria, reached Ambar, the landlords of the place came out to meet him in zeal of their love, faithfulness and respect, no sooner had they seen Imam Ali they got down from their horses and started running in front of him. Imam Ali asked the reason of their strange actions. They replied that it was their custom to show their love and respect in that way. Imam Ali replied: "By God, by your action you do no good whatsoever to your rulers but you tire yourself and put yourself in toils in this world and in trouble in the next. How unfortunate is that exertion, which brings harm here and in the Hereafter and how useful is that ease which keeps you in comfort in this world and away from the Hell in the next.
