"Whoever keeps a horse for the cause of Allah out of faith in Allah and believing the promise of Allah, its feed, water, urine and dung will all count as Hasanat in the balance of his deeds."
Sunan an-Nasa'i Book 28, Hadith 22
← Previous Hadith I was with Ibn 'Abbas and a man asked him: "Did the Messenger of Allah recite during Zuhr and 'Asr?" He said: "No." He said: "Perhaps he used to recite to himself?" He said: "May your face be scratched! This question is worse than the first one. The Messenger of Allah was a slave whose Lord commanded him and he conveyed (the message). By Allah, the Messenger of Allah did not specify anything for us above the people, except for three things: He commanded us to perform Wudu' properly, not to consume charity, and not to mate donkeys with horses."

Sunan an-Nasa'i Book 28, Hadith 21 Next Hadith → It was narrated from Ibn 'Umar that the Messenger of Allah organized a horse race and sent them from Al-Hafya' and its finish line was Thaniyyat Al-Wada'; and he organized a race for horses that had not been made lean, and the course stretched from Ath-Thaniyyah to the Masjid of Banu Zuraiq.
