It is narrated from Sayyiduna Abu Musa al-Ash'ari (may Allah be pleased with him) that Sayyiduna Umar (may Allah be pleased with him) met Sayyidah Asma' bint Umays (may Allah be pleased with her) and said: "How excellent you people would be if you had preceded us in the emigration; so we are better than you." Sayyidah Asma' (may Allah be pleased with her) said: "You were with the Messenger of Allah (peace and blessings be upon him) (in Madinah); he provided mounts for those of you who were on foot and taught those of you who were ignorant, whereas we emigrated for the sake of our religion (in poverty and loneliness)!" Then she said: "I will not go back until I have presented myself before the Messenger of Allah (peace and blessings be upon him)." So she went to him (peace and blessings be upon him) and said: "O Messenger of Allah, I met Umar (may Allah be pleased with him) and he said such-and-such." He (peace and blessings be upon him) said: "No, rather you have the reward of two emigrations: your emigration to Abyssinia and your emigration to Madinah." The chain of this hadith is sahih (authentic), but the two Shaykhs (Bukhari and Muslim) did not record it.
