~7 AH, after the conquest of Khaybar · 7 AH
Details differ across the sources
Reports differ on whether Tufayl ibn Amr and this group of Daws arrived in Madinah during the Battle of Khaybar or only after it.
Abd al-Rahman ibn Sakhr, known as Abu Hurairah, of the tribe of al-Daws in Yemen, had set out on Hijrah to Madinah. Hearing that the Prophet ﷺ was at Khaybar, he diverted there along with two or three other Dawsi Muslims, arriving after the conquest; the same day as the Muhajirun returning from Abyssinia. Though neither group had fought at Khaybar, the Prophet ﷺ gave the Abyssinian emigrants a share of the spoils, and the Dawsis, after the Prophet ﷺ sought the Companions' agreement, were likewise given a share. The delegation was led by Tufayl ibn Amr al-Dawsi RA, chieftain of Daws, who gave up his chieftaincy and his tribe entirely to become a Muhajir and settle permanently in Madinah, and many of his people, moved by his own strength of Iman, chose to emigrate with him.
The beginning of Abu Hurairah RA's three years and a month in the Prophet ﷺ's company, during which he became the most prolific narrator of hadith of any companion.

Set out from Yemen to make Hijrah to Madinah, but on hearing the Messenger of Allah ﷺ was at Khaybar, diverted there instead, arriving, with two or three other Muslims of Daws, after its conquest.
Whoever spreads his garment until I have finished my speech and then gathers it to himself will remember whatever I say.
So I spread my colored garment which I was wearing until the Prophet ﷺ had finished his saying, and then I gathered it to my chest, so I did not forget any of the narrations.
Gave up the chieftaincy of Daws to emigrate to Madinah as a Muhajir, bringing many of his people with him.
Many times I would ask a sahabi a question after he left the masjid: wallahi, I already knew the answer better than him. But the only reason I asked was to drag out the conversation until I reached his doorstep, in hopes that he might invite me in for a meal.
My Muhajir brothers were busy in the marketplace, but I used to stick to the Prophet ﷺ content with what fills my stomach; I was present when they were absent, so I remembered when they forgot. My Ansari brothers were busy with their properties, but I was one of the poor Men of the Suffa, so I remembered when they forgot.
Answering people who wondered why he narrated so many more hadith than the Muhajirun and the Ansar, despite being with the Prophet ﷺ for only the last two years or so.
