The Prophet (ﷺ) arranged for a horse race of the horses which had not been made lean; the area of the race was from Ath-Thaniya to the mosque of Bani Zuraiq. (The sub-narrator said, "`Abdullah bin `Umar was amongst those who participated in that horse race.").
Sahih al-Bukhari Book 56, Hadith 85
← Previous Hadith The Prophet (ﷺ) arranged for a horse race amongst the horses that had been made lean to take place between Al-Hafya'' and Thaniyat Al-Wada` (i.e. names of two places) and the horses which had not been mad.? lean from Ath-Thaniyat to the mosque of Bani Zuraiq. I was also amongst those who took part in that horse race. Sufyan, a sub-narrator, said, "The distance between Al-Hafya and Thaniya Al- Wada` is five or six miles; and between Thaniya and the mosque of Bani Zuraiq is one mile."

Sahih al-Bukhari Book 56, Hadith 84 Next Hadith → "Allah's Messenger (ﷺ) arranged a horse race amongst the horses that had been made lean, letting them start from Al-Hafya' and their limit (distance of running) was up to Thaniyat-al-Wada`. I asked Musa, 'What was the distance between the two places?' Musa replied, 'Six or seven miles. He arranged a race of the horses which had not been made lean sending them from Thaniyat-al-Wada`, and their limit was up to the mosque of Bani Zuraiq.' I asked, 'What was the distance between those two places?' He replied 'One mile or so.' Ibn `Umar was amongst those who participated in that horse race."
