Abu Dawud Book 17, Hadith Number 3552.
Chapter : Not known.
Narated By Zayd ibn Thabit : The Prophet (PBUH) said: If anyone gives something in life-tenancy, it belongs to the one to whom it is given, in his life and after his death; and do not give property to go to the survivor, for if anyone gives something to the survivor, it belongs to him.
