Surah 2. Al-Baqara, Ayah 163

Where the terrible consequences of Evil, i.e., the rejection of God, are mentioned, there is always stress laid on God's attributes of Grace and Mercy. In this case Unity is also stressed, because we have just been told about the Qibla symbol of unity and are about to pass the theme of unity in diversity, in Nature and in the social laws of human society.
