The Norwegian account of Haco's expedition against Scotland, A.D. MCCLXIII‪.‬

At the time that King Haco ruled over Norway, Alexander, the son of William King of Scotland, was then King of Scotland. He was a great Prince, and very ambitious of this world's praise. He sent, from Scotland in the Western sea, two Bishops to King Haco. At first they begged to know if King Haco would give up those territories in the Hebrides, which King Magnus Bare-foot had unjustly wrested from Malcolm, Predecessor to the Scottish King. The King said that Magnus had settled with Malcolm, what districts the Norwegians should have in Scotland, or in the Islands which lay near it. He affirmed, however, that the King of Scotland had no sovereignty in the Hebrides at the time when King Magnus won them from King Godred, and also that King Magnus only asserted his Birthright.
