recorded Kabul as ??????? (Kabura).

According to legend, a lake existed in Kabul, in the middle of which the so-called "Island of Happiness" was located, where a joyous family of musicians resided. According to this same legend, the island became accessible by the order of a king through the construction of a bridge (i.e. "pul" in Persian) made out of straw (i.e. "kah" in Persian). According to this legend the name Kabul was thus formed as a result of these two words combined, i.e. kah + pul. The Concise Oxford Dictionary of World Place
