In imitation of Prophet, Muslims are expected to be merciful, to bring good, and to seek benefits of others - all others - not wish them harm or rejoice in the evill that befalls them. Indeed, the Tradition of Primacy promotes a doctrine of universal, of all-embracing mercy.
Commentators emphasize this point, clarifying that the mercy Muslims are commanded to show is not exclusively for themselves or the righteous amongst them. It extends to all human beings: Jews, Christians, the believing and unbelieving, the upright and the immoral, and it goes beyond the human family to include both the animate and inanimate: birds and animals, even plants and trees.
