Abu Ayyub Sulayman ibn Wahb (Arabic: أبو أيوب سليمان بن وهب) (died July/August 885) was a senior official of the Abbasid Caliphate who served several times as vizier.
His family, the Banu Wahb, were originally Nestorian Christians from Wasit, and had produced secretaries in the caliphal administration since late Umayyad times.
He was first appointed as vizier—by then an almost powerless office due to the internal turmoil and increasing domination of the Turkish military—towards the end of the reign of al-Muhtadi (r. 869–870), and then again in 877 and 878 under al-Mu'tamid (r. 870–892), alternating with his rival al-Hasan ibn Makhlad al-Jarrah.
His inability to counter the mounting financial crisis led to his permanent dismissal and imprisonment, dying in prison in May/June 885.
[1] Sulayman was the founder of a veritable administrative dynasty: his son Ubayd Allah, grandson al-Qasim, and great-grandsons al-Husayn and Muhammad all became viziers.
