Al-Hasan bin Abi al-Hasan relates that he said to Ibn al-Hanzaliyyah (may Allah be pleased with him): Narrate to us a hadith that you heard from the Messenger of Allah (peace and blessings be upon him). He said: I heard the Messenger of Allah (peace and blessings be upon him) say: "Goodness is tied to the forelocks of horses until the Day of Resurrection, and their owners are helped in (looking after) them. Whoever keeps a horse in the path of Allah, spending on it is like one who keeps his hand open in giving charity and does not close it."
