Musannaf Ibn Abi Shaybah 11008 — Reports on hoarded wealth

Sayyiduna Abu Dharr (may Allah be pleased with him) said: I heard the Prophet (peace and blessings be upon him) — or he said: I heard my beloved — say: "In camels (their due) is giving their charity. Whoever gathers a dinar or a dirham, or gold nuggets, or silver, and does not set it aside for a creditor nor spend it in the way of Allah, it is a branding iron with which he will be branded on the Day of Resurrection."
