Holland proceeds to note that with the exception of a single ambiguous reference in the Qur'an, there is no mention of Mecca in any datable text until a century after Muhammad's death. He points out that in the Qur'an, the Prophet appears to address farmers and agriculturalists while his opponents are described as keeping cattle and growing olives and vines. This appears to describe an environment foreign to Mecca, where there was no agriculture; thus Holland posits that the location attributed to Mecca in the Qur'an more closely fits a city in the Negev desert, in what is now southern Israel.
