What is the ruling on reciting Al-Fatiha for the soul of the deceased, and if it is an innovation, what is the response to those who say that Uthman, may Allah be pleased with him, recited Al-Fatiha and another surah at a grave, and is this true?

Acts of worship are prescriptive (tawqifiyyah), and it has not been reported from the Prophet, peace and blessings be upon him, or his Companions that they recited Al-Fatihah for the soul of the deceased. If it had been good, they would have preceded us to it. It is obligatory to abandon innovations and adhere to supplicating for the Muslims in the graves. Scholars have differed regarding the ruling on reciting the Quran at graves; some recommended it, some disliked it, and some deemed it an innovation. Ibn Taymiyyah mentioned that Abu Hanifa, Malik, and Ahmad disliked recitation at the grave in one narration, and permitted it in another because it reached him that Ibn Umar recommended that the beginning and end of Surat Al-Baqarah be recited at his grave, and that recitation at the time of burial is generally reported, but no such report exists for recitation thereafter. In "Al-Furu'" by Ibn Muflih, recitation at the grave and graveyard is not disliked by some, while others disliked it at the time of burial, which is the opinion of the majority of the Salaf, and it was justified by impurity. However, it is authentically reported that Ibn Umar recommended it, so Ahmad retracted his dislike.
