Abdullah bin Ubaydullah bin Abu Mulayka reported,

The descendants of Suhayb, the freed slave of Ibn Judaan, claimed two houses and a room, saying that the Messenger of Allah ﷺ had given them to Suhayb.Marwan asked, "Who will testify for you two regarding this?"They said, "Ibn Umar."So Marwan summoned him, and he testified that the Messenger of Allah ﷺ had indeed given Suhayb two houses and a room. Marwan then ruled in their favor on the basis of his testimony.
