“Allah says: “On that day, nothing will benefit the human being, neither wealth nor children, only the one who brings Allah a sound heart.” A sound heart is one that is free of defects and spiritual blemishes. Though the spiritual heart is centered in the physical heart, the heart being referred to here is the spiritual heart, not the physical heart. In ancient Chinese medicine, the heart houses what is known as “Chen” which is “a spirit.” The Chinese character for “thinking,” “thought,” “love,” “virtue,” and “intending to listen” all contain the ideogram for the heart.”
