Is the money given to a sister to buy a refrigerator considered an ongoing charity (Sadaqah Jariyah) if it is waived to become a gift, knowing that she will use it for household purposes such as drinking water, and does its reward continue after the demise of the giver?

Exempting a sister from debt and contributing to the purchase of a refrigerator for her home is a rewarded act, and its reward accrues to the giver as long as the refrigerator is used, both during their lifetime and after their death. However, it is not considered a perpetual charity (Sadaqah Jariyah) in the jurisprudential sense, which is specific to endowments (waqf).
