Narrated Abu Musa (RA):

Two men had a disputer over an animal, and neither of them had a proof. So Allah's Messenger (ﷺ) gave a ruling that it be divided in halves between them. [Reported by Ahmad, Abu Dawud and an-Nasa'i, and the wording is his (an-Nasa'i) who said that it's chain of narrators is Jayyid (good)].

وَعَنْ أَبَى مُوسَى [ اَلْأَشْعَرِيِّ ] ‏- رضى الله عنه ‏- { أَنَّ رَجُلَيْنِ اِخْتَصَمَا إِلَى رَسُولِ اَللَّهِ ‏- صلى الله عليه وسلم ‏-فِي دَابَّةٍ, لَيْسَ لِوَاحِدٍ مِنْهُمَا بَيِّنَةٌ, فَقَضَى بِهَا رَسُولُ اَللَّهِ > [1]‏ [2]‏ .‏ بَيْنَهُمَا نِصْفَيْنِ } رَوَاهُ أَحْمَدُ, وَأَبُو دَاوُدَ, وَالنَّسَائِيُّ وَهَذَا لَفْظُهُ, وَقَالَ: إِسْنَادُهُ جَيِّد ٌ [3]‏ .‏
