Is it permissible to invoke mercy upon the owners of graves at which religious innovations (bid'ah) are committed?

Question:
He asks: Is it permissible to invoke mercy upon some of the deceased, such as al-Badawi, al-Jilani, and others, whose graves are circumambulated, given that he bears no sin for what these ignorant people do?

Answer:
The one who called people to worship himself before his death: no mercy is invoked for him, and no supplication is made for him; rather, supplication is made against him. As for the one who was a righteous, upright man and did not call people to worship himself, but they did this to him after his death, then he is sought to be forgiven and supplication is made for him. For example, 'Abd al-Qadir al-Jilani was one of the righteous among the imams, and he did not order people to call upon him. If he had ordered people to worship him, he would be among the false gods (taghut), one of the types of false gods who call people to worship themselves. As for the one who used to deny this in his lifetime, and when he died they did this to him—they did this to the prophets and to the righteous, and they deny it against them. Yes.
