Is it permissible to dedicate the reward of seeking forgiveness (Istighfar) and remembrance (Dhikr) to one's parents, whether they are alive or deceased?

"Donating the reward of acts of worship to living individuals is a matter of scholarly disagreement. The relied-upon opinion among the Hanbalis permits donating the reward of any act of devotion to a Muslim, whether living or deceased. According to this view, a person can donate the reward of their remembrance of Allah (dhikr) and seeking forgiveness (istighfar) to their parents and others, whether they are alive or deceased. As for the other opinion, which is the preponderant one and the view of the majority of scholars, it holds that donating the reward of an act is permissible for the deceased but not for the living."
