 i heard muhammad ibn alhasan mus`ab say i had a friend from banu makhzum who was a chess player. i mentioned him to abu al`abbas `abdullah ibn tahir and he said bring him. so i said to almakhzumi prepare to meet abu al`abbas who was wellmannered and wellmannered. so i went out to meet him and he entered. when abu al`abbas saw him he stopped and saw him from afar then he turned away without speaking to him. he said this is a man of good manners go out to meet him and play chess with him in my presence.
