Then I turned my face to Amr ibn Obeid and said: "O learned man, I have just come now and I am a stranger. Do you allow me to ask you some questions?" He allowed me. Then I began my questions as follows: Do you have eyes? My son, what sort of a question is this which you ask of me! There is no need to ask some thing which you are seeing yourself! All my questions are like this. Ask my son, however much your questions may be foolish.

I would ask provided you reply to my all questions whatever they might be. Very well, ask! Do you have eyes? Yes. What do you do with your eyes? I see colours and figures. Do you have a nose? Yes. What do you do with your nose? I smell. Do you have a mouth? Yes. What do you do with your mouth? I partake of the victuals and beverages. Do you have a tongue also? Yes, I do. What do you do with it? I speak with the help of my tongue. Do you have ears? Yes. What do you do with your ears?

I listen to sounds. What about hands? Do you have hands too? Yes, I do. What is the use of your hands? I accomplish heavy works with their help. I feel the softness and hardness of a thing by touching with them. Do you have legs also? Yes I do. What benefit do they give you? I go from one place to another by the help of them. All right, tell me do you have a heart? Yes, I do. When you have all the apparent parts of your body, then what do you do with your heart?

With the help of my heart, I judge their acts and their effects upon my body and senses. Is it not possible that these parts of your body were not in need of a heart as all parts of your body were already in good condition? No, how it is possible that a human being be without a heart? A human being who is well and all parts of his body function properly, is no longer in need of a heart.

O son, what happens if these parts of the body may be misled in doing their duties or their actions maybe doubtful. For example; if the sense of smelling may not be clear regarding what it has smelled; or the eye regarding whatever it has seen; likewise the sense of taste regarding whatever it has tasted or the ear regarding whatever it has heard; and likewise the sense of touch regarding whatever it has touched.

Then they consult with the heart and the heart which is like the capital of a country, checks and judges and puts that doubt aside.
