As for his manners, then they were those of a man, a scholar who practiced what he preached, and he never permitted anyone to backbite in his gathering.

He was most noble and apathetic to what the life of this world had to offer. His was always truthful in speech, and most sincere - always prepared to change his point of view if presented with evidence.

He sought importance in seeking knowledge, and all fields of knowledge were just a means, as for the Book of Allaah, then it was the goal.

It was witnessed by those who frequented his lessons that his knowledge of the Book of Allaah was so strong and vast, that should anyone mention to him an aayah, then he would immediately respond with the aayah before and after it.
