al-Arba‘un al-Abdal al-Tusa‘iyyat li al-Bukhari wa Muslim (Arabic: الأربعون الأبدال التساعيات للبخاري ومسلم أو أحدهما, lit. 'The Forty Substitute Hadiths with Nine-Link Chains for al-Bukhari and Muslim') is a hadith collection compiled by the Egyptian scholar Abd al-Mumin ibn Khalaf al-Dumyati (d. 705 AH / 1306 CE) . It gathers forty narrations transmitted through elevated nine-link isnads (tusā‘iyyāt) that provide alternate, high-ranking transmission pathways corresponding to narrations found in Sahih al-Bukhari and Sahih Muslim .
Method and Contents
The work belongs to the forty-hadith genre (al-arba‘īniyyāt) and focuses on technical isnad elevation (‘uluww) . Each entry presents a prophetic tradition where al-Dumyati maintains an unbroken chain of nine intermediaries between himself and the Prophet ﷺ . These narrations serve as "substitutes" (abdāl), "agreements" (muwāfaqāt), or "handshakes" (muṣāfaḥāt) with respect to the core compilations of the canonical tradition . Introductory verses prefacing sections of the manuscript summarize its layout, highlighting instances such as an agreement corresponding to al-Nasai in the first hadith, a chain equivalent to an immediate encounter (muṣāfaḥa) with Muslim ibn al-Hajjaj in the second, and an agreement corresponding to al-Tirmidhi following the twentieth .
Following each hadith, al-Dumyati provides analytical commentary on the transmission pathways . He identifies corresponding citations across major collections—including Sahih al-Bukhari, Sahih Muslim, the Sunan of al-Tirmidhi, al-Nasai, and Ibn Majah—and notes where his route bypasses intermediaries to achieve higher transmission status . His annotations also record biographical milestones, birth and death dates of central narrators and canonical authors, and the locations where he personally heard these traditions, including Baghdad, Alexandria, Aleppo, and Mecca .
Transmission and Manuscripts
The book is recorded in classical bio-bibliographical inventories among al-Dumyati's specialized hadith compilations, including lists transmitted by his students and contemporaries such as al-Tujibi, al-Birzali, and al-Wadi Ashi .
A surviving manuscript copy was preserved in al-Maktaba al-Khalidiyya in Jerusalem, bearing audition notes indicating it was read back to al-Dumyati in 688 AH .
