Some beggars stood at the door of a Nahwu expert's house. Then they knocked on the door and the nahwu expert said, "Who knocked on the door?" The beggar replied, "A sail (beggar)." The nahwu expert said, "Yansharifu! (Go away)." The beggar said, "My name is Ahmad (he means that Ahmad's name belongs to the isim ghair munsharif, which is a noun that cannot be given tanwin). So the nahwu expert said to his assistant," Give Sibawaih (a famous nahwu expert) harakat kasrah! "

Note: The word insharafa yansharifu in Arabic has many meanings, including 'to go' or a noun (isim) that accepts harakat tanwin. Among the characteristics of isim ghoir munsharif is not accepting harakat kasrah. However, Sibawaih said that the ones which were classified as isim ghair munsharif could be given harakat kasrah
