Compassion is the most frequently occurring word in the Qur’an with each of its 114 chapters (except the 9th) beginning with the invocation ‘In the name of God, the Compassionate, the Merciful…’ At the heart of Muslim belief is the principal of tawhid or oneness. This oneness, or unity, has been described as dominating the mind in Islam, while the heart is intrinsically linked to the concept of compassion. “My Mercy encompasses all things” (Qur’an 7:156). “My mercy takes precedence over my anger” (hadith qudsi, a saying in which God speaks through the Prophet). Islam sees the sentiments of love and compassion … as expressions of the interconnected oneness of all human beings, reflecting the oneness and unity of God.
