The Prophet (ﷺ) said, "Horses are always the source of good, namely, rewards (in the Hereafter) and booty, till the Day of Resurrection."
Sahih al-Bukhari Book 57, Hadith 28
← Previous Hadith I heard Allah's Messenger (ﷺ) saying, "Some people spend Allah's Wealth (i.e. Muslim's wealth) in an unjust manner; such people will be put in the (Hell) Fire on the Day of Resurrection."

Sahih al-Bukhari Book 57, Hadith 27 Next Hadith → Allah's Messenger (ﷺ) said, "When Khosrau is ruined, there will be no Khosrau after him; and when Caesar is ruined, there will be no Caesar after him. By Him in Whose Hands my life is, you will spend their treasures in Allah's Cause."

Sahih al-Bukhari Book 57, Hadith 29
