The ruling on completing the recitation of the Qur'an to mark the anniversary of a deceased person's death, or on purchasing a house or the like

Question:
May Allah reward you and grant you good. The sister, may Allah protect her, from Libya says: We have what is called in the colloquial language al-Khalifah. Yes. It is that when a man dies and a year passes since his death, they bring reciters of the Qur'an who recite in the house every year on the day he died, on the same day he died, I mean? Knowing that they also perform this completion of the recitation when someone buys a new house, or a new car, or other things, claiming that it brings blessing, even though the one who performs it may be a person of righteousness. What is the ruling on this practice? May Allah reward you with good.

Answer:
This practice is a bid'ah (religious innovation). Performing a completion of the Qur'an recitation on these occasions, whether it is the passing of a year since the deceased's death and the belief that it benefits the deceased, or completing the Qur'an when moving into a house, or buying a car, all of this is among the newly invented innovations for which Allah has not sent down any authority. What is required of us is to read the Qur'an, to recite the Qur'an, and to persist in reading it, without assigning it a specific order, time, or occasion. This does not benefit the dead; because it is not prescribed, rather it is a bid'ah, and what is a bid'ah harms and does not benefit.
And if they want to benefit the deceased, they should give in charity the amount they spend on the completion of the recitation and on the reciters. They should give it to the needy with the intention of the reward going to the deceased, and that will benefit him by the permission of Allah the Exalted.
