     (The Dove's Necklace or The Ring of the Dove); In classical Arabic literary tradition, the dove represented love, or romance, while the ring refers to a necklace. In essence, it is the "necklace of love". The book is meant to adorn one's love. It is inspired by ishq (defined by Hakim Bey as "crazed, hopeless passion"), and treats equally of desire both for males and females, but cautions the reader against breaking religious injunctions and praises remaining chaste.


Ibn Hazm also wrote more than ten books on medicine.

A number of his works have been translated, including:
  • Al-Akhlaq wa al-Siyar fi Mudawat al-Nufus (Morals and Right Conduct in the Healing of Souls")

Ethics

In his book, In Pursuit of Virtue, ibn Hazm had urged his readers with the following:
Do not use your energy except for a cause more noble than yourself. Such a cause cannot be found except in Almighty God Himself: to preach the truth, to defend womanhood, to repel humiliation which your creator has not imposed upon you, to help the oppressed. Anyone who uses his energy for the sake of the vanities of the world is like someone who exchanges gemstones for gravel.

Poetry

A poem, or fragment of a poem, by him is preserved in Ibn Said al-Maghribi's Pennants of the Champions:
You came to me just before
the Christians rang their bells.
The half-moon was rising
looking like an old man's eyebrow
or a delicate instep.

And although it was still night
when you came a rainbow
gleamed on the horizon,
showing as many colours
as a peacock's tail.
