Spanish chroniclers ignored the Córdoba martyrs despite their propaganda potential.

Evidence

Bede’s account of the reign of Heraclius provides some telling examples of his method and interests. He devotes twenty-three lines (in the Patrologia Latina edition) to the martyrdom of the monk Anastasius, decapitated by the Persian emperor Chosroes, then fourteen lines to the mission of Paulinus of York to King Edwin of Northumbria, then seven to a controversy between the Pope and the Scots about the dating of Easter. Here are the three subjects that Bede finds worthy of commemoration during the reign of Heraclius. In the context of Anastasius’s martyrdom, he does indeed mention in passing that Heraclius defeated the Persians but makes not the slightest allusion to his defeats against the Arabs at Ajnâdayn (634) or Yarmûk (636). Bede only notices the Muslim conquests as they reach the Western Mediterranean. — John V. Tolan, Saracens, 451 (#qualifies, via linked claim)

Perhaps it is not surprising that the Muslim reason for the institution of the fast was lost sight of, or, more often, never known. Only the Cluniacs, Peter the Venerable, and the Annotator from whom he presumably gained his knowledge, mention that the fast marks the Night of Power, laylat al-qadar, on which the Qur’an descended upon Muhammad; and even they did not know that the Night occurs (once) during the fast, but spoke of the descent of the Qur’an, as occurring throughout the thirty nights of the month. — Norman Daniel, Islam and the West, 1234 (#qualifies, via linked claim)
