question: What present day country would Muhammad ibn Abbas be from?
answer: present-day central Afghanistan
context: Title: Abbas ibn Shith
  Passage: Abbas ibn Shith was the king of the Ghurid dynasty.  He overthrew his uncle Abu Ali ibn Muhammad in 1035, and ascended the Ghurid throne.  During his later reign, the nobles of Ghor requested aid from the Ghaznavid sultan Ibrahim, who marched towards Ghor and deposed Abbas ibn Shith.  Abbas was succeeded by his son Muhammad ibn Abbas, who agreed to pay tribute to the Ghaznavids.
  Title: Shahriyar ibn Abbas
  Passage: Kiya Abu'l-Fawaris Shahriyar ibn Abbas ibn Shahriyar (Persian: کیا ابوالحسن فاو شهریار بن عباس بن شهریار‎ ‎ ), better simply known as Shahriyar ibn Abbas (شهریار بن عباس ) was a Bavandid prince, who is solely known for being mentioned in the inscription on the mausoleum in Savadkuh, known as the Lajim Tower.  The mausoleum was constructed in 1022, where he was most already likely dead.  The person who ordered the construction was his mother Chihrazad, whilst the name of the architect was a certain al-Husayn ibn Ali.  In the inscription, Shahriyar is labeled as "Client of the Commander of the Faithful" ("mawlā amīr al-muʾminīn").  However, he is not called "ispahbad", which was the title used by the Bavandid rulers, and thus it is dubious if he ever ruled.
  Title: Ghurid dynasty
  Passage: The Ghurids or Ghorids (Persian: سلسله غوریان‎ ‎ ; self-designation: شنسبانی , "Shansabānī") were a dynasty of Eastern Iranian descent (presumably Tajik, but the exact ethnic origin is uncertain), from the Ghor region of present-day central Afghanistan.  The dynasty converted to Sunni Islam from Buddhism, after the conquest of Ghor by the Ghaznavid emperor Mahmud of Ghazni in 1011.  Abu Ali ibn Muhammad (reigned 1011–1035) was the first Muslim king of the Ghurid dynasty to construct mosques and Islamic schools in Ghor.
  Title: Tanwir al-Miqbas
  Passage: Tanwir al-Miqbas min Tafsir Ibn Abbas (Arabic: تنوير المقباس من تفسير بن عباس) is a tafsir, attributed to Abd-Allah ibn Abbas, but which contains much atypical content for a tafsir of the sahabah.  It is said to have been collected by Abu Tahir Muhammad ibn Yaqub al-Fayruz Aabadi (1329–1414).
  Title: Emirate of Diriyah
  Passage: The Emirate of Diriyah was the first Saudi state.  It was established in the year 1744 (1157 A.H.) when Muhammad ibn Abd al-Wahhab and Prince Muhammad bin Saud formed an alliance to establish a new religious sect and political sovereignty against orthodox Sunni Islam as they understood it.  In 1744, both Muhammed bin Abd Al Wahhab and Muhammad bin Saud took an oath to achieve their goal.  Marriage between Muhammad bin Saud's son, Abdul-Aziz bin Muhammad, and the daughter of the Muhammad ibn Abd al-Wahhab helped to seal the pact between their families which has lasted through the centuries to the present day.
  Title: Muhammad bin Saud
  Passage: Muhammad ibn Saud (Arabic: محمد بن سعود ‎ ‎ ; died 1765), also known as Ibn Saud, was the emir of Ad-Diriyyah and is considered the founder of the First Saudi State and the Saud dynasty, which are technically named for his father – Saud ibn Muhammad ibn Muqrin (died 1725).  Ibn Saud's family (then known as the Al Muqrin) traced its descent to the tribe of Banu Audi and Hanifa tribes but, despite popular misconceptions, Muhammad ibn Saud was neither a nomadic bedouin nor was he a tribal leader.  Rather, he was the chief ("emir") of an agricultural settlement near modern-day Riyadh, called Diriyah.  Furthermore, he was a competent and ambitious desert warrior.
  Title: Fadl ibn Abbas
  Passage: Fadl ibn Abbas (614-639) was a brother of Abdullah ibn Abbas and was a cousin of the Islamic prophet Muhammad.
  Title: Muhammad ibn Abbas

He succeeded his father Abbas ibn Shith in 1060, after the latter was deposed by the Ghaznavid sultan Ibrahim.  When Muhammad ascended the throne, he agreed to pay tribute to the Ghaznavids.  Not much is known about him, he was succeeded by his son Qutb al-din Hasan.
  Title: Muhammad ibn Mikal
  Passage: Muhammad ibn Mikal was an Iranian nobleman from the Mikalid family, who served as a military commander of the Tahirid dynasty.  He was the son of Mikal, a nobleman who had left Iraq and settled in Khurasan, and could trace his descent back to the Sogdian ruler Divashtich.  Muhammad also had a brother named Shah ibn Mikal, who, during his early career, along with Muhammad, played an important role under the Tahirid ruler Abdallah ibn Tahir al-Khurasani.  In 864, the Alid Hasan ibn Zayd conquered Tabaristan from the Tahirids, while another Alid named Muhammad ibn Ja'far ibn al-Hasan expelled the Tahirid governor of Ray, and captured the city.  The Tahirid ruler Muhammad ibn Tahir shortly sent an army from Khurasan under Muhammad ibn Mikal, who managed to recapture the city and capture Muhammad ibn Ja'far.  Hasan, however, quickly made a counter-attack under his Dailamite general Wajin, who managed to rout the army of Muhammad ibn Mikal, and kill the latter.
  Title: Abd Allah ibn Abbas
