Silsilat al-Ahadith al-Sahihah

It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: "If I had gold equal to the mountain of Uhud, I would love (to spend it in the way of truth so quickly) that not even three nights would pass and nothing of it would remain with me except for that portion which I would keep to pay off a debt."
