There were two men, one was blind, and the other was bald. God’s angel appeared in the form of a man before the bald man and asked him, ‘What do you wish for?’ The bald man said that he would like to have hair and be wealthy. The angel passed his hand over his head, and by the Grace of God, hair grew on the bald man’s head. The bald man also became wealthy and gained servants.
Then the angel went to the blind man and asked, ‘What do you wish for?’ The blind man asked for eyesight so that he does not stumble around. He wished for wealth as well so that he was not dependent on anyone. The angel passed his hand over his eyes, and his vision was restored. He was also given wealth.
Later on, with God’s command, the same angel, in the disguise of a beggar, appeared to the bald and the blind to test them. He begged the bald man for alms. The bald man responded in a harsh tone and rebuffed: ‘Be off. Many beggars like you wander around.’ The angel passed his hand over the head of the bald, turning him bald again. He lost all his wealth and became penniless.
The same angel came to the blind, too, in the form of a beggar, who had become wealthy and had regained his eyesight. The angel asked for charity. The blind said, ‘Everything that I have is given to me by the Almighty God and is His property. You take it all.’ The Almighty God blessed him with even more wealth.
Moral of the story: My dear children! You must remember to thank God for whatever He has bestowed on you and appreciate what has been given to you. Never rebuff anyone who asks for alms. Charity is a bliss. The one who asks for help, he must be given his due share. God is then delighted and multiplies His blessings.
