Once the Holy Prophet (SAW) told his companion that there were three men of Banu Israel. One of them was leper, the other bald and the third blind. Allah, in order to test them, sent an angel to them. First of all the angel came to the leper and asked him what he desired most. The leper replied that he wanted fair colour, beautiful skin and to be relieved from that disease due to which people hated him and kept him away. The angel passed his hand over the body of the leper and immediately the disease disappeared. The angel then asked him which wealth we liked most. The leper named camel. So the angel gave him a pregnant she-camel and prayed to Allah to bless his wealth.
Then the angel went to the bald man and asked him what he liked? The bald man replied that he wanted good hair and to be cured from baldness. The angel passed his hand over the head of the bald man and immediately good hair cropped up on his head. Then the angel asked him which wealth he desired. The man asked for a cow. The angel gave him a pregnant cow and blessed his wealth.
In the end the angel went to the blind man and asked him as to what he wanted. The blind man replied that he wished Allah to cure his blindness so that he might see others. The angel passed his hand over his eyes and immediately his eyesight was restored by Allah. The angel asked him which wealth he desired. The man desired for a goat. The angel gave him a goat and blessed his wealth also.
The animals of the three persons flourished and prospered to such an extent that their respective parts of the land were full of them.
After some time the angel again came to them under orders of Allah. First he went to the ex-leper and posed before him as traveller and said that all of his provisions of the journey had exhausted and was left with nothing to return home. He asked for a camel in the name of Allah, who had cured him of leprosy. The ex-leper scolded & snubbed him coldly saying that he had other responsibilities and could not spare a camel for him. The angel reminded him of his former position as a leper and that Allah, by his Benevolence has cured his disease and blessed him with all the wealth. The man replied bluntly that he had inherited the wealth from his fore-fathers. Thereupon the angel cursed him to return to his previous position as he was a liar.
Then the angel went to the ex-bald man and asked him the same question. He, too, replied in the same manner as the leper had done. The angel cursed him also.
In the end the angel went to the ex-blind man and relating his misfortune begged him for a goat in the name of Allah. The man replied. “Of course I was blind. Allah has blessed me with eye-sight. Take as many goats as you like. By Allah! I will not refuse. “The angel replied that he only wanted to test him.
Look! Due to their thanklessness and ungratefulness the first two persons were deprived of the blessings of Allah and were reduced to their former position and were cursed in this world and the Hereafter.
