Hazrat Sha’bi narrates that regarding a person whose eye is injured, the saying of Ali (may Allah be pleased with him) is mentioned that he showed him an egg. Sha’bi asked: If he uses his seeing eye more, Ali replied: He may see as much as he can with it. I asked: If he uses his injured eye less, he replied: He should not see less than what he can, rather it is better that he sees as much as he can easily, then the loss will be assessed (an estimate will be made).
