Maybe the Rifian ruler would as a means of preventing the Viking expedition from conquering and ransacking his kingdom in the first place, he invites the entire group to settle down in his lands and a small tribute to the Viking ruler in exchange of peace and local control over whatever lands they settle in while also serving in the ruler's army whenever there was a need for extra men. The Vikings like the idea and accept, settling down in the area. Most of them would cohabit with the local women since I presume this group of Vikings were mostly pagan so intermarriage wouldn't be acceptable unless they convert to Islam which most of them probably wouldn't.
