He died on the twentieth of Muharram in 598 AH.
It is also said that he was born in Rajab of 513 AH.
Ibn al-Najjar (1) said: “He was quick-witted, intelligent, and had an extraordinary memory for rare reports. On one occasion he fashioned a chess set that weighed two kharubat, with a razzah made of ivory and ebony. As he grew older his temper worsened; he became quarrelsome and used to abuse the father who had supervised his hadith audition. His religiosity was scant—may Allah pardon him.”
