What is the ruling on making du'a' (supplication) at the grave after the burial of the deceased?

Question:
What is the ruling on making du'a' (supplication) at the grave after the burial of the deceased? And what is the ruling on reciting al-Fatihah (Surat al-Fatihah) with the takbir (saying Allahu akbar) when following the funeral procession?

Answer:
Reciting al-Fatihah (Surat al-Fatihah) at the grave, or reciting it with the funeral procession while walking, and raising the voice with the takbir (saying Allahu akbar), all of this is from bid'ah (religious innovation). This is bid'ah (religious innovation) . Rather, the one who follows the funeral procession should be in a state of tranquility, not raising his voice, and he should make du'a' (supplication) for the deceased, seek forgiveness for him, for himself, and for the Muslims, and not raise his voice. And making du'a' (supplication) at the grave. Making du'a' (supplication) for the deceased at the grave, at his grave, is this prescribed?
That you stand at the grave of your brother and make du'a' (supplication) for him for forgiveness and mercy. As for making du'a' (supplication) at the grave for yourself, making du'a' (supplication) for yourself at the grave, this is bid'ah (religious innovation) and a means of shirk (associating partners with Allah), and it is not permissible. Yes.
