The Prophet (ﷺ) gave the verdict that `Umra is for the one to whom it is presented.
Sahih al-Bukhari Book 51, Hadith 57
← Previous Hadith The sons of Suhaib, (Suhaib, who was the freed slave of Bani Jud'an) claimed that Allah's Messenger (ﷺ) had given two houses and one room to Suhaib. Marwan asked, "Who will testify to your claim?" They replied that Ibn 'Umar would do so. Marwan sent for Ibn 'Umar who testified that Allah's Messenger (ﷺ) had really given Suhaib two houses and a room. So, Marwan gave the verdict (in favour of Suhaib's sons), because of (Ibn 'Umar's) witness.
