When Mola Ali (a.s) Ibn e Abu Talib (a.s), marching at the head of his army towards Syria, reached Ambaar, the landlords of the place came out to meet him in zeal of their love, faithfulness and respect, no sooner had they seen Mola Ali (a.s) Ibn e Abu Talib (a.s) they got down from their horses and started running in front of him.
Mola Ali (a.s) Ibn e Abu Talib (a.s) asked the reason of their strange actions. They replied that it was their custom to show their love and respect in that way. Mola Ali (a.s) Ibn e Abu Talib (a.s) replied:
"By Allah, 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."
