Sayyida Asma bint Yazid (may Allah be pleased with her) narrated from the Messenger of Allah (peace and blessings be upon him), he said: "Whoever ties a horse in the way of Allah (for jihad), and spends on it with the intention of reward, then its being full, its being hungry, its being thirsty, its being quenched, and its urination and defecation will all be in his scale (of deeds) on the Day of Judgment."
