Abdulaziz ibn Muhammad Al Saud

Imam Abdulaziz ibn Muhammad Al Saud (1720–1803) was the second ruler of the Emirate of Diriyah and the first Saudi state, succeeding his father in 1765 ^{1 2}.

Abdulaziz was a son of Muhammad ibn Saud, the state's founder, and was devoted to learning from his youth ². He travelled to Muhammad ibn Abd al-Wahhab at al-Uyayna and remained at his side in study and campaigning until, in the Arabic article's words, he was among his most prominent students ². He also married his teacher's daughter, becoming his son-in-law ¹. On his father's death in 1765 he succeeded him as imam ¹.

Abdulaziz had been the state's chief military commander from his father's time, and under him the state took Riyadh in 1773, al-Qatif in 1794 and al-Hasa in 1795 and raided as far as Syria, Iraq and Yemen by 1800; his son Saud led the sack of Karbala in 1802, and Taif and Mecca fell in 1803 ¹. The Arabic article adds that his sway reached Qatar and Bahrain, that his state ran some 1,500 kilometres, that it was noted for security and rectitude, that his epistles on tawhid were preserved in Ulama Najd, and that al-Shawkani praised him ².

Abdulaziz was assassinated at Diriyah in November 1803 while leading the afternoon prayer in the mosque of Turaif, by a Kurdish darwish from Amadiya avenging Karbala, and was buried in the al-Oud cemetery at Riyadh ^{1 2}. His son Saud succeeded him ¹.

No source read names a legal school for the man himself. That he was Muhammad ibn Abd al-Wahhab's student and son-in-law and the reform movement's imam and leader is a matter of leadership, kinship and discipleship, none of which settles a school by itself, and Wikidata gives only Islam ^{1 3}. The Hanbali character of the movement's fiqh tradition is context, stated in his record and here, not a settlement; his faith is therefore recorded as unknown.

The two Muhammads must not be blended — his father and predecessor is Muhammad ibn Saud, and his teacher and father-in-law is Muhammad ibn Abd al-Wahhab, and his edges are written accordingly ^{1 2}. His birth year and his place among his brothers are contested — the English article gives 1720 and makes him the eldest son, the Arabic article pairs his life with 1133–1218 AH and 1721–1803 CE and makes him the third son ^{1 2 3}. For the assassination day, the English infobox gives 12 November and Wikidata 1 November, so the month alone is built ^{1 3}. Diriyah has no museum place record yet, so he carries no place edge.
