PROPHET MUHAMMAD (ﷺ) said:
Good will remain (as a permanent quality) in the foreheads of horses till the Day of Resurrection.

PROPHET MUHAMMAD (ﷺ) said:
No stake (prize) is acceptable except in archery, racing a camel, and racing a horse.

PROPHET MUHAMMAD (ﷺ) said:
If somebody keeps a horse in Allah's Cause motivated by his faith in Allah and his belief in His Promise, then he will be rewarded on the Day of Resurrection for what the horse has eaten or drunk and for its dung and urine.

Narrated Anas bin Malik:
Once the people of Medina were frightened, so the Prophet (ﷺ) rode a horse belonging to Abu Talha and it ran slowly, or was of narrow paces. When he returned, he said, "I found your (i.e. Abu Talha's) horse very fast. After that the horse could not be surpassed in running.'

Narrated Anas:
The 'Prophet was the best and the bravest amongst the people. Once the people of Medina got terrified at night, so they went in the direction of the noise (that terrified them). The Prophet (ﷺ) met them (on his way back) after he had found out the truth. He was riding an unsaddled horse belonging to Abu Talha and a sword was hanging by his neck, and he was saying, "Don't be afraid! Don't be afraid!" He further said, "I found it (i.e. the horse) very fast," or said, "This horse is very fast."

Narrated Abu 'Is-haq from Musa bin `Uqba from Mafia from Ibn `Umar who said:
"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."

Narrated Nafi`:
`Abdullah said, "The Prophet (ﷺ) arranged for a horse race, and the prepared horses were given less food for a few days before the race to win the race, and were allowed to run from Al-Hafya to Thaniyat-al- Wada`, and the unprepared horses were allowed to run between Thaniyat-al-Wada` and the mosque of Bani Zuraiq," `Abdullah was one of those who participated in the race.
