What did Ibn 'Umar say when someone mentioned that he had migrated before his father `Umar (saw)?
 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."
