The Prophet ﷺ said: If one enters a horse with two others when he is not certain that it cannot be beaten, it is not gambling; but when one enters a horse with two others when he is certain it cannot be beaten, it is gambling.  

عَنِ النَّبِيِّ ﷺ قَالَ مَنْ أَدْخَلَ فَرَسًا بَيْنَ فَرَسَيْنِ يَعْنِي وَهُوَ لاَ يُؤْمَنُ أَنْ يُسْبَقَ فَلَيْسَ بِقِمَارٍ وَمَنْ أَدْخَلَ فَرَسًا بَيْنَ فَرَسَيْنِ وَقَدْ أَمِنَ أَنْ يُسْبَقَ فَهُوَ قِمَارٌ  

“Whoever enters a horse (in a race) between two other horses, not knowing whether it will win, that is not gambling. But whoever enters a horse (in race) between two other horses, certain that it will win, that is gambling.”  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ أَدْخَلَ فَرَسًا بَيْنَ فَرَسَيْنِ وَهُوَ لاَ يَأْمَنُ أَنْ يَسْبِقَ فَلَيْسَ بِقِمَارٍ وَمَنْ أَدْخَلَ فَرَسًا بَيْنَ فَرَسَيْنِ وَهُوَ يَأْمَنُ أَنْ يَسْبِقَ فَهُوَ قِمَارٌ  

The Prophet ﷺ said: If one enters a horse with two others when he is not certain that it cannot be beaten, it is not gambling; but when one enters a horse with two others when he is certain it cannot be beaten, it is gambling. (Using translation from Abū Dāʾūd 2579)   

عَنِ النَّبِيِّ ﷺ قَالَ مَنْ أَدْخَلَ فَرَسًا بَيْنَ فَرَسَيْنِ وَهُوَ لَا يَأْمَنُ أَنْ يَسْبِقَ فَلَا بَأْسَ بِهِ وَمَنْ أَدْخَلَ فَرَسًا بَيْنَ فَرَسَيْنِ وَقَدْ أَمِنَ أَنْ يَسْبِقَ فَهُوَ قِمَارٌ  

The Prophet ﷺ said: If one enters a horse with two others when he is not certain that it cannot be beaten, it is not gambling; but when one enters a horse with two others when he is certain it cannot be beaten, it is gambling. (Using translation from Abū Dāʾūd 2579)   

عَنِ النَّبِيِّ ﷺ قَالَ مَنْ أَدْخَلَ فَرَسًا بَيْنَ فَرَسَيْنِ وَقَدْ أَمِنَ أَنْ يَسْبِقَ فَهُوَ قِمَارٌ وَمَنْ أَدْخَلَ فَرَسًا بَيْنَ فَرَسَيْنِ وَهُوَ لَا يَأْمَنُ أَنْ يَسْبِقَ فَلَيْسَ بِقِمَارٍ  

[Machine] The Messenger of Allah ﷺ said, "Whoever enters a horse between two horses and is not afraid of being left behind, then it is gambling. And whoever enters a horse between two horses and is afraid of being left behind, then it is not gambling." This was specifically mentioned by Sufyan ibn Husayn and Sa'id ibn Bashir from Az-Zuhri, and it was narrated by Abu Dawood in his book of Sunan.  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ مَنْ أَدْخَلَ فَرَسًا بَيْنَ فَرَسَيْنِ وَهُوَ لَا يَخَافُ أَنْ يُسْبَقَ فَهُوَ قِمَارٌ وَمَنْ أَدْخَلَ فَرَسًا بَيْنَ فَرَسَيْنِ وَهُوَ يَخَافُ أَنْ يُسْبَقَ فَلَيْسَ بِقِمَارٍ تَفَرَّدَ بِهِ سُفْيَانُ بْنُ حُسَيْنٍ وَسَعِيدُ بْنُ بَشِيرٍ عَنِ الزُّهْرِيِّ وَقَدْ أَخْرَجَهُمَا أَبُو دَاوُدَ فِي كِتَابِ السُّنَنِ  

"مَنْ أَدْخَل فرَسًا بين فَرَسَينِ وَهُو لَا يَأمنُ أَنْ يَسْبِقَ، فَليس بِقَمَّار، ومنْ أَدْخَلَ فَرَسًا بَين فَرسَينِ وَقَدْ أَمِنَه أَنْ يَسْبِقَ فهُوَ قَمارٌ".
