Examination of Eye Sight, the Power of Talking and that of Smelling
It has been reported in the book Ajaibul Ahkam that a man was struck on the head of by another person with something hard. The man who was struck claimed that he had lost his eye sight as well as his power of talking and that of smelling as a result of that stroke.
Hazrat Ali (A) said if the man was correct, he deserved to receive penalty on all the three counts. When asked as to how was it possible to check that the claim of the man in question was correct, Hazrat Ali (A) said as follows:-
(i) “As regards his eye sight the man will be made to stand in the open and cast his eyes on the sun. In case he could and did not shut his eyes his claim of losing his eye sight would be correct.”
(ii) In the case of the power of smelling he would be made to inhale the smoke of a patch of burning cotton. If he does not make signs of feeling sensation in his nose and also does not shed tears by the effect thereof his claim of losing his power of smell would be deemed as intact.
(iii) In the case of power of talking the tip of his tongue would be pricked with a small needle. If the drop of blood which would come out of his tongue is red he would be deemed to possess power of talking and only as malingering there about. But if the drop of blood is black he would be deemed as correct in his claim. He also advised to examine all the dumbs in the same manner. (Wafi, Kafi and Turaqi Hakmia, p.49).
