Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) narrates that he heard the Prophet (peace and blessings be upon him) say: "Indeed, when Allah Almighty is pleased with a servant, He praises him sevenfold for good which he did not even do; and when He is displeased with a servant, He mentions him sevenfold for evil which he did not even do."
