He said to him: You have two characteristics which Allah likes: gentleness and deliberation.
He asked: Have I acquired them or has Allah has created (them) my nature? He replied: No, Allah has created (them) in your nature.
He then said: Praise be to Allah Who has created in my nature two characteristics which Allah and His Apostle like.
