There is a well-known story of Halim, the most eminent Sufi of the past, who became so well-known that the world began to revere him for his generosity and love. Once the King of Persia became jealous of him, seeing him so adored by everybody, and he promised the chief of the assassins some part of his territory if he would cut off the head of Halim and bring it to him. The assassin left this country with great pleasure expecting the reward. After many days' journey he arrived in the city where Halim lived. Halim, as was his custom, went to see if there were any stranger in the city whom he might in any way assist.
