What does the deceased benefit when we visit their grave and supplicate for them?

Visiting the deceased and greeting them is from the Sunnah, and it benefits the deceased by alleviating their burden. As for whether the deceased finds comfort in visitors, scholars have differed on this. Supplicating for the deceased is beneficial, reaches them, and its reward reaches them without dispute. It is a cause for alleviating their burden and forgiving their sins, as is seeking forgiveness for them and giving charity on their behalf. It has been authentically reported that the Prophet, peace and blessings be upon him, used to visit the deceased and supplicate for them.
