Before diving into the PDF search, it is crucial to understand why this book is so important.
Al-Mughni (Arabic: المغني, meaning "The Enricher" or "The Sufficer") is a 15-volume encyclopedic work of Fiqh (Islamic jurisprudence). Authored by Muwaffaq al-Din Abdullah ibn Ahmad ibn Qudamah (1147-1223 CE / 541-620 AH), a towering scholar of the Hanbali school, the book is not just a list of rulings. It is a masterpiece of comparative Fiqh.
The short answer: No. As of 2025, there is no complete, authorized, free public domain PDF of the entire Al-Mughni translated into English.
The Arabic text (in PDF format) is widely available for free on sites like shamela.ws and archive.org. However, the English translation is a massive undertaking that scholars and publishers are still working on.
If you downloaded the Arabic PDF of Al-Mughni (available at waqfeya.com or shamela.ws), you can make it usable for English speakers with modern tools:
Be extremely cautious. Here are common traps:
Safety Tip: Only download PDFs from reputable Islamic libraries like Kalamullah.com, Archive.org (check user reviews), or official publisher sites (Dar-us-Salam, Turath Publishing).
Status: Volumes 1, 2, and sometimes 3 only. Format: Hardcover & Digital PDF (legally purchasable). Content: Covers the Book of Purification (Taharah) and the Book of Prayer (Salah). Verdict: Excellent translation, but only covers ~10% of the whole work. You can buy a legal PDF from their website or Amazon Kindle.
The original Arabic Al-Mughni runs over 6,000 to 9,000 pages across 15 large volumes. A complete, high-quality English translation would be an estimated 10,000–12,000 pages. This is a logistical and financial undertaking comparable to translating the entire Encyclopaedia Britannica.
