Hazrat Abdullah bin Ja'far narrates that one day the Prophet صلی اللہ علیہ وسلم made me ride behind him and confided a secret to me which I will not disclose to anyone, and it was your preference that for relieving yourself, a mound or a cluster of date-palm trees would conceal you. Once, you entered a grove of the Ansar's trees and saw a camel there. When the camel saw you, it knelt down and its eyes began to flow with tears. So the Prophet صلی اللہ علیہ وسلم passed his hand over its back and neck, and it became calm. You asked, "Whose camel is this?" or you said, "Who is the owner of this camel?" An Ansari said, "O Messenger of Allah صلی اللہ علیہ وسلم ! It is mine." You said, "Treat it well, for it has complained to me that you keep it hungry and always burden it with work."
