Abū Yaʻqūb Isḥāq ibn Ibrāhīm ibn Mukhallad al-Ḥanẓalī (), commonly known as Isḥāq ibn Rāhwayh (; 161 AH – 238 AH), was a jurist and imam of Khorasan. Along with Sufyan al-Thawri and Dawud al-Zahiri, he is cited in Lisanu-l-Arab (also spelled Lisan al-Arab) for taking the stance that once a man marries a slave and has children with her both she and the child are free, and the child cannot be enslaved. This was against the opinion of most Islamic scholars of jurisprudence of the time. He was also a fellow student and a friend of Ahmad ibn Hanbal who accompanied him on his travels to seek knowledge. Influence Ibn Rahwayh helped to inspire al-Bukhari to compile what is now commonly known as Sahih al-Bukhari. Al-Bukhari stated, "We were with our teacher Ishaq ibn Rahwayh when he said: &apos;if only someone would compile a compact book for the authentic ahadith of the prophet, peace and blessings of Allah be upon him.&apos; That stirred something in my heart so I set out in compiling al-Jami as-Sahih". Works Ibn Rahwayh's books on tafsir, ahadith and fiqh include: Al-Musnad (المسند) Al-Jāmiʻ al-Kabīr (الجامع الكبير) Al-Jāmiʻ al-Ṣaghir (الجامع الصغير) Al-Muṣannaf (المصنف) Al-ʻIlm (العلم) At-Tafsīr al-Kabīr (التفسير الكبير): lost work References 770s births 852 deaths People from Merv Hadith scholars Atharis Hadith compilers Sunni imams Persian Sunni Muslim scholars of Islam 9th-century Muslim scholars of Islam People from Nishapur Quranic exegesis scholars Iranian scholars Muhaddiths from Nishapur 8th-century writers 9th-century writers 9th-century jurists 9th-century Iranian people
