Sayyiduna al-Ash'ath bin Qays (may Allah be pleased with him) said: I heard the Prophet (peace and blessings be upon him) say: "Whoever seizes the property of a Muslim man by a false oath will meet Allah, the Mighty and Majestic, while He is angry with him; then (as He wills) He will either pardon him or punish him."
