Sahih al-Bukhari 2630

It is related that Anas ibn Malik said, "When the Muhajirun came to Madina from Makka, they possessed nothing. The Ansar were people of land and property. The Ansar shared with them on the basis that they would give them the fruits of their property every year and they [the Muhajirun] would spare them from work and agriculture." His mother was the mother of Anas and the mother of Sulaym and also the mother of 'Abdullah ibn Abi Talha. The mother of Anas gave the Messenger of Allah, may Allah bless him and grant him peace, some date-palms which the Prophet, may Allah bless him and grant him peace, later gave to Umm Ayman, his client, the mother of Usama ibn Zayd. Ibn Shihab said that Anas ibn Malik reported to him that when the Prophet, may Allah bless him and grant him peace, finished fighting the people of Khaybar and returned to Madina, the Muhajirun returned to the Ansar their maniha gifts whose fruits they used to enjoy. The Prophet, may Allah bless him and grant him peace, returned her date-palms to his mother and the Messenger of Allah, may Allah bless him and grant him peace, gave Umm Ayman some of the trees of his garden in their place. This is related from Yunus and he said, "In their place from his own property."
