Is reciting Al-Fatiha for the soul of the deceased permissible, and does it have a basis in the Prophetic Sunnah?

The more sound opinion is that the reward for reciting the Quran reaches the deceased. However, specifying a time, place, manner, or number that the Lawgiver did not specify makes the act unlawful. Thus, reciting Al-Fatiha when remembering the deceased or at a condolence gathering is an innovation that has no basis in the Sunnah. The Sunnah is to seek forgiveness for the deceased and to ask for steadfastness for them.
