Original: This was also the case in medieval Arabic literature , where a longer penis was preferred , as described in an Arabian Nights tale called '' Ali with the Large Member '' . As a witty satire of this fantasy , the 9th century Afro-Arab author Al-Jahiz wrote : '' If the length of the penis were a sign of honor , then the mule would belong to the ( honorable tribe of ) Quraysh '' .
