وَعَنْ عِمْرَانَ بْنِ حُصَيْنٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «لَا جَلَبَ وَلَا جَنَبَ» . زَادَ يَحْيَى فِي حَدِيثِهِ: «فِي الرِّهَانِ» . رَوَاهُ أَبُو دَاوُدَ وَالنَّسَائِيُّ وَرَوَاهُ التِّرْمِذِيُّ مَعَ زِيَادَة فِي بَاب «الْغَضَب»
English Translation
‘Imran b. Husain reported God’s Messenger as saying, “There must be no shouting or leading another horse at one’s side."* Yahya added in his tradition, “when racing for a wager." * There must be no shouting to urge one’s horse on, and one must not take a horse alongside him to which he may transfer if he is afraid his horse may be beaten. Abu Dawud and Nasa’i transmitted it, and Tirmidhi transmitted it with an addition in the section on seizing forcibly.
