About the Author

Abū al-Qāsim Muhammad ibn Juzayy al-Kalbī

Abū al-Qāsim Muhammad ibn Juzayy al-Kalbī was among the most distinguished Mālikī scholars of Islamic Spain. Serving as the Khatīb of the Great Mosque of Granada, he excelled across numerous Islamic sciences, including jurisprudence, Qur'anic exegesis, Hadith, Arabic language, and Islamic literature. A scholar of exceptional intellect and unwavering courage, he dedicated both his pen and his life to the service of Islam, ultimately attaining martyrdom while defending the Muslim lands at the Battle of Tarīfah.

His writings continue to inspire generations of Muslims, preserving a legacy of scholarship that remains as relevant today as it was centuries ago.

Why Zaman Books Stands Out

Zaman Books was founded on a clear mission: to make Islamic history clear, accessible, and open to everyone. Their beautifully produced books bring to life the rich legacy of Muslim civilisation – from the saga of Islamic Sicily and the golden age of al-Andalus to the majestic Ottoman Empire and the inspiring stories of Women of Islam.

With dedicated series such as The Essentials (for adults seeking scholarly depth) and Zaman Kids (created with care, love, and devotion to give children authentic heroes and role models), Zaman Books offers something for every member of the family. Their translations of classical works, such as Ibn Hazm’s The Book of the Healing of Souls, combine rigorous academic excellence with engaging, readable prose that connects readers directly to the beauty of Islamic tradition.
