graveyard

Q: Is there any Saheeh Ahadeeth in which there is a specific virtue or it is more virtuous of visiting the Graveyard on a Friday (before or after Jumuah prayer) or the eve of Friday?

Q: My father passed away. I want to ask that may I go to his grave as I don't have a husband, brother or son. To sum up I have no man in my family so is there any leniency in Islam?

Q: I'm having problems with my marriage and I told all my problems to one Mufti who lives in Ajmer, India. I met him online. I have very serious problems in my family. So Mufti Arfaz says that wazifa won't solve all problems and He told me that he has to sacrifice a goat for me. He will go at night to graveyard and sacrifice the goat there, but he needs money for the goat. After I sacrifice the goat, I will get married within 48 hours. But my family found out that I tried to send money to Mufti Arfaz and I told them what he told me. They said that whatever he does is haraam. Even though his methods really work. They tell me not to speak to him and my dad fought with him. My parents just can't understand my sitiation that I'm helpless. But who is right Mufti Arfaz or my family?
