牙刺瓦赤、赛典赤·赡思丁、匿赞马丁是蒙哥朝燕京行省回回官员，他们的势力在忽必烈朝阿合马当政期间均遭到不同程度的打击或排挤，牙剌瓦赤之子阿里别为阿合马所杀，匿赞马丁则身系大都监狱，而赛典赤·赡思丁离开权力中枢，最后老死云南。这说明回回政治集团内部并非铁板一块，也存在着矛盾与冲突，对权力的争夺是产生这种矛盾、冲突的主要因素，其他如种族、地域、伊斯兰教派所产生的影响也不可忽视。“,”Yalavach, Sayyid All Omer Shams al- Din and Nizam- ad- Din are Islam officials of Yan- jing Province of Mengke Khan period. Their forces in Ahmad period are hit and excluded in different lev- els. Ali Bek, the son of Yalavach was killed by Ahmad. Nizam- ad- Din was arrested in Great Capital of Yuan. Sayyid All Omer Shams al- Din left the central power and finally died in Yunnan. This shows that the internal of Islam political group also has conflict due to the power struggles and other factors such as race, region and Islamic sect.
