Ruling on reading Qur’aan over graves, and saying du’aa’ for oneself at the graveside
Question

                What is the ruling on reading Qur’aan over graves? Saying du’aa’ for the deceased at the graveside? Saying du’aa’ for oneself at the graveside?.
Praise be to Allah.
    Reading the Holy Qur’aan at the graveside is bid’ah. It was 
    not narrated from the Prophet  (peace and blessings of Allaah be upon 
    him) or from his companions. As it is not narrated from the Prophet  
    (peace and blessings of Allaah be upon him) or from his companions, then we 
    should not introduce it by ourselves, because the Prophet  (peace and 
    blessings of Allaah be upon him) said, according to a saheeh report: “Every 
    introduced matter is an innovation, and every innovation is a going astray, 
    and every going astray will be in the Fire.” What the Muslims must do is to 
    follow the example of the earlier generations, the Sahaabah and those who 
    followed them in truth, so that they will be following goodness and true 
    guidance, because it is proven that the Prophet  (peace and blessings of 
    Allaah be upon him) said: “The best of speech is the Book of Allaah and the 
    best of guidance is the guidance of Muhammad  (peace and blessings of 
    Allaah be upon him).” 

    As for saying du’aa’ for the deceased at the graveside, there 
    is nothing wrong with that. A person may stand at the graveside and say 
    whatever du’aa’s he can, such as saying, “O Allaah, forgive him; O Allaah, 
    have mercy on him; O Allaah, admit him to Paradise; O Allaah, make his grave 
    spacious” and so on. 

    With regard to a person saying du’aa’ for himself at the 
    graveside, if he does it deliberately then it is also an innovation 
    (bid’ah), because no place is specified as a place for du’aa’ unless there 
    is a text concerning it. If there is no text concerning it and no Sunnah has 
    been narrated concerning it, then that – i.e., singling out a place for 
    du’aa’, no matter what the place is – is a bid’ah. End quote.
