It was narrated that Anas said: “The Messenger of Allah صلی اللہ علیہ وآلہ وسلم had a she-camel called Al-’Adba’ which could not be beaten. One day a Bedouin came on a riding-camel and beat her (in a race). The Muslims were upset by that, and when he saw the expressions on their faces they said: ‘Messenger of Allah صلی اللہ علیہ وآلہ وسلم, Al-’Adba’ has been beaten.’ He said: ‘It is a right upon Allah that nothing is raised in this world except He lowers it.” (Sahih)
