The Book of Gifts
Ṣaḥīḥ Muslim 4188
أَيُّمَا رَجُلٍ أُعْمِرَ عُمْرَى لَهُ وَلِعَقِبِهِ فَإِنَّهَا لِلَّذِي أُعْطِيَهَا لاَ تَرْجِعُ إِلَى الَّذِي أَعْطَاهَا لأَنَّهُ أَعْطَى عَطَاءً وَقَعَتْ فِيهِ الْمَوَارِيثُ

The full narration
Jabir b. 'Abdullah (Allah be pleased with them) reported Allah's Messenger (ﷺ) as saying:"Any man who is given a gift for life, it belongs to him and his heirs. It belongs to the one to whom it is given, and does not go back to the one who gave it, because he has given it in such a way that it is subject to the rules of inheritance
