Musnad Ahmad 30:3442

Yazid narrated to us, Ibn Abi Dhi'b informed us, from al-Maqburi, from Abu Hurayrah, from the Prophet, peace and blessings of Allah be upon him, who said: "Whoever has an injustice [committed] against his brother, regarding his honor or his wealth, let him seek absolution for it today, before it is taken [from him] at a time when there will be neither dinar nor dirham. If he has a righteous deed, it will be taken from him according to the extent of his injustice. And if he has none, the bad deeds of his companion will be taken and placed upon him." [Abdullah narrated to us, my father narrated to me, saying]: And he said in Baghdad: "Before a day comes when there is neither dinar nor dirham there."
