Is buying a private cemetery plot for burying family members considered an ongoing charity (Sadaqah Jariyah)?

Waiving land for burial is considered an ongoing charity (sadaqah jariyah). An ongoing charity is an endowment (waqf) whose principal remains intact and whose reward does not cease as long as its benefit continues. This is realized in waiving land for the burial of the dead. It is mentioned in the noble Hadith that among the deeds and good works that accrue to a believer after his death are: "a mosque he built, or a house he built for a wayfarer, or a river he caused to flow, or a charity he gave from his wealth during his health and lifetime, which will accrue to him after his death."
