Editing Abu Bakr ibn Umar (section)

===Dating===
Following [[Ibn Abi Zar]], Abu Bakr ibn Umar's death has been commonly dated to 1087.{{sfn|Conrad|Fisher|1982|p=22}} This is supported by numismatic evidence, with coins minted in Sijilmassa in Abu Bakr's name until that date.<ref>{{cite book |last1=Hazard |first1=Harry |title=The Numismatic History of Late Medieval North Africa |date=1952 |publisher=American Numismatic Society |page=61-2 |url=https://www.scribd.com/document/213852433/The-numismatic-history-of-late-medieval-North-Africa-by-Harry-W-Hazard |access-date=5 November 2024}}</ref> [[Ibn 'Idhari]], however, records him dying only 3 years after his return to the desert, sometime in 1075 or 1076. The clear exaggerations in Ibn Abi Zar's account are perhaps a reason to view his dates with skepticism,{{sfn|Conrad|Fisher|1982|p=35}} as well as the fact that the campaign against Ghana was possibly led by Abu Bakr's son, Yahya.{{sfn|Burkhalter|1992|p=111}}
<blockquote><p>No historian has yet accounted for the ease with which Almoravid historiography has appropriated Ibn Idhari's chronology—this, at the expense of that passed on by Ibn Abi Zar and Ibn Khaldun—at all junctures except the date he provides Abu Bakr's death.{{sfn|Burkhalter|1992|p=127}}</p></blockquote>
