In this commentary Ibn Kathir differentiates between the end of the Earth and the supposed "place in the sky" where the sun sets (the "resting place" of the sun. Ibn Kathir contends that Dhul-Qarnayn did reach the farthest place that could be travelled west but not the "resting place" of the sun and he goes on to mention that the People of the Book (Jews and Christians) tell myths about Dhul-Qarnayn travelling so far beyond the end of the Earth that the sun was "behind him." This shows that Ibn Kathir was aware of the Christian legends and it suggests that Ibn Kathir considered Christian myths about Alexander to be referring to the same figure as the Dhul-Qarnayn mentioned in the Qu'an.
