حدثني محمد بن صباح  أو بلغني عنه  حدثنا إسماعيل، عن عاصم، عن أبي عثمان، قال سمعت ابن عمر  رضى الله عنهما  إذا قيل له هاجر قبل أبيه يغضب، قال وقدمت أنا وعمر على رسول الله صلى الله عليه وسلم فوجدناه قائلا فرجعنا إلى المنزل، فأرسلني عمر وقال اذهب فانظر هل استيقظ فأتيته، فدخلت عليه فبايعته، ثم انطلقت إلى عمر، فأخبرته أنه قد استيقظ، فانطلقنا إليه نهرول هرولة حتى دخل عليه فبايعه ثم بايعته‏.‏
 Narrated Abu `Uthman:                     I heard that Ibn `Umar used to become angry if someone mentioned that he had migrated before his father (`Umar), and he used to say, " `Umar and I came to Allah's Apostle and found him having his midday rest, so we returned home. Then `Umar sent me again (to the Prophet ) and said, 'Go and see whether he is awake.' I went to him and entered his place and gave him the pledge of allegiance. Then I went back to `Umar and informed him that the Prophet was awake. So we both went, running slowly, and when `Umar entered his place, he gave him the pledge of allegiance and thereafter I too gave him the pledge of allegiance."
