It has been narrated on the authority of Anas b. Malik who said: When the Muhajirs migrated from Mecca to Medina; they came (in a state that) they had not anything (i. e. money) in theirhands, while the Ansar possessed lands and date palms. They divided their properties with the Muhajirs. The Ansar divided and gave them on the condition that they would give half the fruit from the orchards every year, and the Muhajirs would recompense them by working with them and putting in labour. The mother of Anas b. Malik was called Umm Sulaim and she was also the mother of 'Abdullah b. Talha who was a brother of Anas from his mother's side. The mother of Anas had given the Messenger of Allah (ﷺ) her date-palms. He bestowed them upon Umm Aiman, the slave-girl who had been freed by him and was the mother of Usama b. Zaid. When the Messenger of Allah (ﷺ) had finished the war with the people of Khaibar and returned to Medina, the Muhajirs returned to the Ansar all the gifts which they had given them out of the fruits. (Anas b. Malik said: ) The Messenger of. Allah (ﷺ) returned to my mother her date-palms and gave to Umm Aiman instead of them date-palms from his orchard. Ibn Shihab says that Umm Aiman was the mother of Usama b. Zaid who was the slave-girl of 'Abdullah b. 'Abd-ul-Muttalib and hailed from Abyssinia. When Amina gave birth to the Messenger of Allah (ﷺ) after the death of his father, Umm Aiman used to nurse him until he grew up. He (later on) freed her and married her to Zaid b. Haritha. She died five months after the death of the Messenger of Allah (ﷺ).
