English translation
2624. Narrated 'Abdullāh bin 'Ubaidullāh bin Abū Mulaika: The sons of Ṣuhaib, (Ṣuhaib, who was the freed slave of Bani Jud'ān) claimed that Allāh's Messenger ﷺ had given two houses and one room to Ṣuhaib. Marwān asked, "Who will testify your claim?" They replied that Ibn 'Umar would do so. Marwān sent for Ibn 'Umar who testified that Allāh's Messenger ﷺ had really given Ṣuhaib two houses and a room. So, Marwān gave the verdict (in favour of Ṣuhaib's sons), because of (Ibn 'Umar's) witness.
