Mishkat al-Masabih 11 Business Transactions كتاب البيوع 232

وَعَنِ ابْنِ عُمَرَ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَقْطَعَ لِلزُّبَيْرِ حُضْرَ فَرَسِهِ فَأَجْرَى فَرَسَهَ حَتَّى قَامَ ثُمَّ رَمَى بِسَوْطِهِ فَقَالَ: «أَعْطُوهُ مِنْ حَيْثُ بَلَغَ السَّوْطُ» . رَوَاهُ أَبُو دَاوُد

Ibn ‘Umar said that the Prophet assigned to az-Zubair the land his horse could cover at a run. He made his horse run, and when it stopped he threw his whip. He then said, “Give it to him up to the spot his whip has reached.” Abu Dawud transmitted it.
