Following are a few cases relating to physics decided by Hazrat Ali (A) :
1. Compensation Judgement in Case of the Loss of an Eye
Once a slave of Hazrat Othman (RA) hit the eye of a bedouin resulting in the loss of his eye. The bedouine took the matter to Hazrat Othman, (AR) who tried to patch up the matter by offering full penalty of the eye of the complainant, but he would not agree.
Hazrat Otman (RA) then offered him the double of the amount fixed as penalty for an eye by the religious law, but the bedouine would still not agree to the offer but insisted on taking th eye of the slave out as an exchange of his eye which was lost by the hit of the slave.
HazratOthman (RA) was confused as what to do thereafter and referred the case to Hazrat Ali (A) who first tried to make the bedouine to accept the offer, but when he would not agree despite all the possible efforts of even the Holy Imam (A), he sent for a patch of cotton put in the water and placed it in the eye of the slave, leaving the pupil open. Then, he sent for a mirror and put it in the sun and ordered the slave to see the sun therein with that eye till the sight thereof was lost, but the eye ball remained intact (Wafi, vol. 9, p. 99)
