Abu Hurayrah (may Allah be pleased with him) reported that he heard the Prophet (may Allah's peace and blessings be upon him) say: ''There were three (men) from the Children of Israel: a leper, a bald-headed, and a blind. Allah wanted to test them, so He sent to them an angel. The angel went to the leper and said: 'Which thing do you like most?' He said: 'A good color, fine skin, and to get rid of what makes me disgusting in the eyes of people.' He wiped over his body, so his illness went away and he was given a good color and fine skin. He (the angel) said: 'Which wealth do you like most?' He said: 'Camels, or cows (the sub-narrator Is'hāq was in doubt).' So he was given a she-camel in an advanced stage of pregnancy, and he (the angel) said: 'May Allah bless it for you.' Then he went to the bald-headed man and said: 'Which thing do you like most?' He said: 'Good hair, and to get rid of what makes me disgusting in the eyes of people.' He wiped over his head, so his condition went away and he was given good hair. Then the angel said: 'Which wealth do you like most?' He said: 'Cows or camels.' So, he was given a pregnant cow and the angel said: 'May Allah bless it for you.' Then he went to the blind man and said: 'Which thing do you like most?' He said: 'That Allah restores to me my eyesight so that I can see people.' He wiped over his eyes, so Allah restored to him his eyesight. Then the angel said: 'Which wealth do you like most?' He said: 'Sheep.' So he was given a pregnant ewe. The three then had offspring from the ones given to them: one had a valley of camels, the second a valley of cows, and the third a valley of sheep. Later, the angel went to the leper in his (past) appearance and said: 'I am a poor person, and I am running out of provision in my journey, so I cannot reach my destination except with the help of Allah and then your favor. I ask you by the One Who gave you good color, fine skin and wealth to give me one camel to carry me in my journey.' He said: 'I have many rights to fulfill.' Thereupon, he (the angel) said: 'It seems to me that I know you. Were you not a leper whom people found disgusting, and a poor man then Allah gave you wealth?' He said: 'I have inherited this wealth from my forefathers.' Thereupon, the angel said: 'If you are lying, may Allah change you to your past condition.' He then went in his (past) appearance to the bald-headed man and said to him the same as what he had said to the leper, and he replied to him in the same way the leper did. So, the angel said: 'If you are lying, may Allah change you to your past condition.' Then he went in his (past) appearance to the blind man and said: 'I am a poor man and a wayfarer. My provisions have run short in my journey, and today there is no way to reach my destination except with the help of Allah and then with your help. So, I ask you by the One Who restored to you your eyesight to give me one sheep by which I should be able to make provisions for the journey.' The man said: 'I was blind and Allah restored to me my eyesight. You may take whatever you like and leave whatever you like. By Allah, I shall not stand in your way today for what you take in the name of Allah.' Thereupon, the angel said: 'Keep your property. The fact is that the three of you were put to test. Now, Allah is pleased with you and is displeased with your two companions.'"
