It was narrated that Anas said:"The Messenger of Allah 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: 'O Messenger of Allah, Al-'Adba' has been beaten.' He said: 'It is a right upon Allah that nothing is raised in this world except He lowers it.'"
أَخْبَرَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، عَنْ خَالِدٍ، قَالَ حَدَّثَنَا حُمَيْدٌ، عَنْ أَنَسٍ، قَالَ كَانَتْ لِرَسُولِ اللَّهِ صلى الله عليه وسلم نَاقَةٌ تُسَمَّى الْعَضْبَاءَ لاَ تُسْبَقُ فَجَاءَ أَعْرَابِيٌّ عَلَى قَعُودٍ فَسَبَقَهَا فَشَقَّ عَلَى الْمُسْلِمِينَ فَلَمَّا رَأَى مَا فِي وُجُوهِهِمْ قَالُوا يَا رَسُولَ اللَّهِ سُبِقَتِ الْعَضْبَاءُ . قَالَ " إِنَّ حَقًّا عَلَى اللَّهِ أَنْ لاَ يَرْتَفِعَ مِنَ الدُّنْيَا شَىْءٌ إِلاَّ وَضَعَهُ " .
