Ishaq bin Ibrahim bin Makhlad bin Rahwayh Abu Ya'qub al-Hanzali al-Marwazi (, 777-778 - 855 CE) commonly known as Ishaq ibn Rahwayh (romanizated: IshÃÂq ibn RÃÂhawayh) was a Sunni Muslim scholar, jurist, muhaddith, exegete, and theologian. A close friend of Ahmad ibn Hanbal, he accompanied him on his travels to seek knowledge, and he was also a teacher of Bukhari and inspired him to compile the Sahih al-Bukhari. Among his only surviving work is al-Musnad, a hadith collection arranged by Companion narrators.
Ishaq belonged to the Adnanite tribe of Banu Tamim. His full lineage is recorded as:
IsḥÃÂq ibn Abë al-Ḥasan IbrÃÂhëm ibn Mukhlad ibn IbrÃÂhëm ibn ÿAbd AllÃÂh ibn Maá¹Âar ibn ÿUbayd AllÃÂh ibn GhÃÂlib ibn ÿAbd al-WÃÂrith ibn ÿUbayd AllÃÂh ibn ÿAá¹Âiyyah ibn Murrah ibn Kaÿb ibn HammÃÂm ibn Asad ibn Murrah ibn ÿAmr ibn ḤanáºÂalah ibn MÃÂlik ibn Zayd ManÃÂt ibn Tamëm ibn Murrah al-ḤanáºÂalë al-Marwazë.
There has long been confusion surrounding his name. Ibn al-Sam'ani stated that his name should read as 'Rahuwayh', but that he was called 'Rahawayh', seemingly because of the difficulty of the á¸Âammah on the letter haâÂÂ. Ibn Khallikan, on the other hand, proposes 'Rahwayh' and 'Rahuya'.
Various stories also surround the origins of his name. In a report, the Tahirid governor Abdallah ibn Tahir demanded an explanation from Ishaq about the genesis of his name. Ishaq went on to explain that his father was born whilst travelling and this is how he came to acquire the epithet 'Rahuwi'.
Ibn Khallikan gives a different version of a similar story. Ishaq's father was born on the road to Mecca. In Persian, the word for road is "", and "wayh" means to find, thus it means 'the one found on the road'. "Ibn RÃÂhwayh" remained a laqab of his descendants.
Ishaq ibn Rahwayh was born in Merv, present-day Mary, Turkmenistan, in the year 161 AH / 777âÂÂ778 CE. He began his studies in Khorasan and then set off on his journey at the age of thirteen. He is reported to have studied in the Hijaz, Yemen, Syria, and reached Iraq in 800 CE. He frequently travelled to Baghdad before settling permanently in Nishapur, where he spent the rest of his life until his death.
Among his most notable teachers are the traditionists Abd Allah ibn al-Mubarak () in Khorasan, Ibn 'Ulayya () and Sufyan ibn ýUyaynah () in the Hijaz, and Waki' ibn al-Jarrah () and Yahya ibn Adam () in Iraq. He was also a contemporary and close colleague of Ahmad Ibn Hanbal and a teacher of Bukhari, Muslim, Abu Dawud, Tirmidhi, and Nasa'i.
Ibn RÃÂhwayh was regarded as one of the foremost scholars of his era. He also used to issue Fatwas (legal verdicts). During his residence in Iraq, he became one of Ahmad Ibn Hanbal's closest companions. He reportedly memorized seventy thousand hadith by heart. His teachings developed into a Sunni legal school, which doesn't survive today.
Being a traditionalist, he was hostile to Ahl al-Ra'y. According to Ibn Qutaybah, Ishaq believed that the Ahl al-Ra'y "abandoned the Quran and Prophetic Sunnah and adhered to qiyas (analogy)," which led them to contradictions and absurdities.
He is reported to dye his beard with Henna.
Ishaq arguably became the most influential of all Bukhari's teachers and influenced him to compile Sahih al-Bukhari.
Bukhari narrates:
The following works are listed in Ibn al-Nadim's Fihrist:
He died on 14th of Sha'ban 238 AH / 29 January 853 CE. Many people wrote Elegies to mourn for his death. His grave was known and visited until at least 10th century.
