Please explain how I "pointed to Khaldun" to justify a claim. I pointed your attention (if it can be called that) to the fact that I raised the topic with regard to Khaldun's 14th century contemporaries, who lived in the 14th century, which is before the 15th century.
Sheesh.
I already documented it in several previous posts, particularly 190. As you are determined to ignore inconvenient facts and records regardless of how many times they are presented to you, posting it again is unlikely to serve any purpose other than to waste my time.
