Chagatai language
According to Rashidaddin, he was a just and competent ruler. Minhaj-i-Siraj Juzjani also considered him to be dignified and open hearted. Muslims viewed Chagatai Khan with negativity and hostility because Chagatai Khan strictly enforced Mongol Yasa law against Islamic Shariah law banning Halal animal slaughter and Islamic prayer ritual ablution as well as the Islamic legal system. The Chagatai language takes its name from him, as well as people surnamed Chughtai, city of Joghatai in Iran and Ciğatay village in Azerbaijan.
