Al-Hidayah fi Sharh Bidayat al-Mubtadi (d. 593 AH/1197 CE) (, al-Hidāyah fī Sharḥ Bidāyat al-Mubtadī), commonly referred to as al-Hidayah The Guidance, is a 12th-century Hanafi juridical work by Shaykh al-Islam Burhan al-Din al-Farghani al-Marghinani that is considered an authoritative guide to fiqh among Muslims throughout the world, based on Mukhtasar of Al-Quduri Islamic law. Author is from Russia.
The Hidayah represents the refined distilled and authentic version of a legal tradition developed over many centuries. It presents the corpus of Hanafi law in its approved and preferred form and forges an organic link with the other schools of law. There is no book that can match the power of al-Hidayyah as a teaching manual. Education in Islamic law is not complete without this book. Accordingly, each and every Islamic seminary, whatever its affiliation, imparts instruction in Islamic law through al-Hiddayah. The primary reason for its popularity is the reliability of its statements and the soundness of its legal reasoning. Most researchers and scholars first consult al-Hiddayah before they move to another source, and it is arguably the most popular and important work in the entire fiqh literature.
A new English translation of the original Arabic text was published by Amal Press in 2006, covering the ritual and family law sections, and amounting to about 40% of the original work (the volumes on civil, contractual and criminal law were largely omitted).
