Sayyiduna Abu al-Darda' (may Allah be pleased with him) narrated a marfu' hadith: "Whatever Allah has declared lawful or unlawful in His Book, that alone is lawful or unlawful; and what He kept silent about, He has overlooked (that is, it is a concession). So accept Allah's concession, for He is not forgetful." Then he recited this verse: "And your Lord is not forgetful." [Surah Maryam: 64]
