al-Mukhtalitin lil-Alai

Kitab al-Mukhtalitin (Arabic: كتاب المختلطين, The Book of Confused Narrators) is a specialized biographical work in Hadith transmitter criticism by the Shafi'i hadith master Salah al-Din al-Alai (694–761 AH / 1295–1359 CE) Athar Ikhtilaf al-Asanid …+1. It provides a concise alphabetical survey of hadith transmitters who suffered cognitive deterioration (ikhtilat) in late life, establishing criteria for evaluating the reliability of their transmissions Athar Ikhtilaf al-Asanid …+1.

Background and Purpose

The study of mukhtalitun emerged as an essential branch of hadith criticism aimed at distinguishing narrations taken from trustworthy transmitters before the onset of memory loss, advanced senility, blindness, or trauma from those recorded after Manhaj al-Naqd fi Ulum al…+1. In his Ulum al-Hadith, Ibn al-Salah remarked that although examining impaired transmitters was a noble and vital field, he knew of no dedicated independent monograph on the subject al-Ightibat biman Rumi mi…+1. In response to Ibn al-Salah's observation, al-Alai composed this concise treatise (juz') al-Ightibat biman Rumi mi…. Later scholars noted that Abu Bakr al-Hazimi (d. 584 AH) had also compiled a work on the topic titled Tuhfat al-Mustafid, which Ibn al-Salah had apparently not seen al-Wasit fi Ulum wa Musta…+1.

Structure and Typology

Al-Alai arranged the biographical notices alphabetically (ala huruf al-mu'jam) by narrator name al-Ightibat biman Rumi mi…+1. In his theoretical introduction, he categorized narrators who suffered deterioration in late life into three classes:

1. Unaffected Authorities: Narrators whose confusion caused no weakness and did not diminish their standing, either because the episode was brief and limited—such as Sufyan ibn Uyaynah and Ishaq ibn Rahawayh—or because they ceased narrating entirely during their impairment, safeguarding their reports from delusion, such as Jarir ibn Hazim and Affan ibn Muslim Athar Ikhtilaf al-Asanid …+1.
2. Previously Criticized Narrators: Transmitters who were already contested or deemed weak before their impairment, so the onset of confusion merely compounded their unreliability, such as Abdullah ibn Lahi'ah and Muhammad ibn Jabir al-Suhaymi Athar Ikhtilaf al-Asanid …+1.
3. Impaired Reliable Authorities: Transmitters whose reports were originally authoritative (muhtajj bihi), but subsequent senility or confusion caused irregularity (idtirab) in their later transmissions; relying on their hadiths requires differentiating what their students received before the deterioration from what was heard after Athar Ikhtilaf al-Asanid …+1.

Reception and Influence

Al-Alai transmitted the treatise directly to his students, including Zayn al-Din al-Iraqi al-Ightibat biman Rumi mi…. Subsequent hadith scholars made extensive use of its framework: Ibn Hajar al-Asqalani authored a supplement (dhayl) to it al-Wasit fi Ulum wa Musta…+1, and Sibt Ibn al-Ajami (al-Burhan al-Halabi, d. 841 AH) expanded upon the topic in his work al-Ightibat bi-ma'rifat man rumiya bi-l-ikhtilat Manhaj al-Naqd fi Ulum al…+1.

A manuscript of the work is preserved in the Köprülü Library in Istanbul Khizanat al-Turath - Fihr…. It was edited by Rifat Fawzi Abd al-Muttalib and Ali Abd al-Basit Mazid and published by Maktabat al-Khanji in Cairo in 1417 AH / 1996 CE Fatima bint al-Nabi - صلى…+1.
