Is dedicating the reward of reciting the entire Holy Quran to a deceased mother considered an ongoing charity for her?

Continuous charity (صدقة جارية) is the endowment (waqf), which is the tying up of the principal and dedicating its usufruct. Dedicating the reward of reciting the Quran to your mother is not continuous charity, but it is one of the righteous deeds whose reward is permissible to dedicate to the deceased, according to the preponderant opinion.
