Narrated Anas:
حَدَّثَنَا مَالِكُ بْنُ إِسْمَاعِيلَ ، حَدَّثَنَا زُهَيْرٌ ، عَنْ حُمَيْدٍ ، عَنْ أَنَسٍ ـ رضى الله عنه ـ قَالَ كَانَ لِلنَّبِيِّ صلى الله عليه وسلم نَاقَةٌ تُسَمَّى الْعَضْبَاءَ لاَ تُسْبَقُ ـ قَالَ حُمَيْدٌ أَوْ لاَ تَكَادُ تُسْبَقُ ـ فَجَاءَ أَعْرَابِيٌّ عَلَى قَعُودٍ فَسَبَقَهَا، فَشَقَّ ذَلِكَ عَلَى الْمُسْلِمِينَ، حَتَّى عَرَفَهُ فَقَالَ " حَقٌّ عَلَى اللَّهِ أَنْ لاَ يَرْتَفِعَ شَىْءٌ مِنَ الدُّنْيَا إِلاَّ وَضَعَهُ " . طَوَّلَهُ مُوسَى عَنْ حَمَّادٍ عَنْ ثَابِتٍ عَنْ أَنَسٍ عَنِ النَّبِيِّ صلى الله عليه وسلم .
The Prophet (ﷺ) had a she camel called Al Adba which could not be excelled in a race. (Humaid, a subnarrator said, "Or could hardly be excelled.") Once a bedouin came riding a camel below six years of age which surpasses it (i.e. Al-`Adba') in the race. The Muslims felt it so much that the Prophet (ﷺ) noticed their distress. He then said, "It is Allah's Law that He brings down whatever rises high in the world."
