"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.'"
أَخْبَرَنِي عَمْرُو بْنُ عُثْمَانَ بْنِ سَعِيدِ بْنِ كَثِيرٍ، قَالَ حَدَّثَنَا بَقِيَّةُ بْنُ الْوَلِيدِ، قَالَ حَدَّثَنَى شُعْبَةُ، قَالَ حَدَّثَنِي حُمَيْدٌ الطَّوِيلُ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ سَابَقَ رَسُولَ اللَّهِ صلى الله عليه وسلم أَعْرَابِيٌّ فَسَبَقَهُ فَكَأَنَّ أَصْحَابَ رَسُولِ اللَّهِ صلى الله عليه وسلم وَجَدُوا فِي أَنْفُسِهِمْ مِنْ ذَلِكَ فَقِيلَ لَهُ فِي ذَلِكَ فَقَالَ
" حَقٌّ عَلَى اللَّهِ أَنْ لاَ يَرْفَعَ شَىْءٌ نَفْسَهُ فِي الدُّنْيَا إِلاَّ وَضَعَهُ اللَّهُ " .
It was narrated that Anas bin Malik said:
"The Messenger of Allah raced with a Bedouin and (the latter) won. It was as if the Companions of the Messenger of Allah were upset by this, so he said: 'It is a right upon Allah that there is nothing that raises itself in this world except that He lowers it.'"
It was narrated from Yahya bin 'Abbad bin 'Abdullah bin Az-Zubair, from his grandfather, that he used to say:
"In the year of Khaibar, the Messenger of Allah allocated four shares to Az-Zubair bin Al-'Awwam: A share of Az-Zubair, a share for the relatives of Safiyyah bint 'Abdul-Muttalib, the mother of Az-Zubair, and two shares for the horse."
