Prophet Muhammad (PBUH) described Surah Yaseen as the "Heart of the Quran." In Islamic tradition, everything has a heart, and the heart of the Quran is Yaseen. This comparison is not arbitrary; just as the heart is vital for the physical body, Surah Yaseen contains the core message of the Quran—Tawheed (Oneness of God), Prophethood, and the reality of the Hereafter.
