Abu Dawud Book 36, Hadith Number 5206.

Narated By al-Wazi’ ibn Zari’ : Umm Aban, daughter of al-Wazi’ ibn Zari’, quoting his grandfather, who was a member of the deputation of AbdulQays, said: When we came to Medina, we raced to be first to dismount and kiss the hand and foot of the Apostle of Allah (PBUH). But al-Mundhir al-Ashajj waited until he came to the bundle of his clothes. He put on his two garments and then he went to the Prophet (PBUH).

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.
