" The Helpers (Ansar) conferred the benefit of 'Umra, upon the Emigrants (Muhajirin), whereupon Allah's Messenger (ﷺ) said: Keep your property to yourselves.
Sahih Muslim Book 24, Hadith 35
← Previous Hadith Keep your property to yourselves and do not squander it, for he who conferred a life grant upon another that property will belong to him upon whom it is conferred whether he lives or dies, and (would pass on) to his successors (as heritage).

Sahih Muslim Book 24, Hadith 34 Next Hadith → This garden has returned to us. The sons of the one who had been given life grant said: This belonged to our father, during his lifetime and in case of his death. They took their dispute to Tariq, the freed slave of 'Uthman. He called Jabir and he gave testimony of Allah's Messenger (ﷺ) having said: Life grant belongs to one who is conferred upon this (privilege). Tariq gave this decision and then wrote to Abd al-Malik and informed him, Jabir bearing witness to it. Abd al-Malik said: Jabir has told the truth. Then Tariq gave a decree and, as a result thereof, it is to this day that the garden belongs to descendants of one who was conferred upon the life grant.
