Once, Abdullah bin Amr (may Allah be pleased with him) came to his father, Amr bin Al-As (may Allah be pleased with him). His father invited his son to eat, but he replied, "I am fasting." He (the father) responded, "I have heard a hadith from the Prophet (peace and blessings be upon him) regarding this matter."
