Sayyiduna al-Ash'ath bin Qays (may Allah be pleased with him) said: Once I bought back my oath for seventy thousand (dirhams), and the reason was that I had heard the Messenger of Allah (peace and blessings be upon him) say: "Whoever takes away the right of a Muslim by a false oath will meet Allah, the Mighty and Majestic, while He is angry with him."
