Father abandoning his children

Q: My friend's mother died last year and they had 8 kids. It was less than a year and the dad fought with his children on purpose and ruined his kids birthday so that he can go Pakistan. It was a planned visit and went Pakistan and got married against his kids wishes. All he does is listens to his wife and has pushed all his kids away from him. He don't listen to the kids and all he does all day is talks to his wife. All he does is listens to that lady and then wants his kids to listen to him. Don't know what she should do? The lady is greedy and wants him to give his lands to her and not to his family. Also all she ever does is asks for money. Her family is greedy but he wont listen. The kids are so lonely and on the verge of doing something wrong?

Istikhaara for marriage

Q: We carried out an istikhara for my son almost a year ago for a college girl he was interested in. The Aalim said no. My son got very disturbed and heard from someone that istikhara can be repeated after some time. During this year almost, he prayed five times and performed umrah with the family and did istikhara himself and saw himself offering prayer. He says he is satisfied and the answer is yes from Almighty Allah. He only resolves around any option confirming his yes but we the parents still wish to seek guidance. We want some responsible authority to say ok before we take decision. Please help us!!

Relatives worshipping snakes

Q: Our relatives mostly are hypocrites. Sometimes they openly say that they worship snakes etc... And also mention that they have jinn's (supernatural powers), they say that they instruct that power to do work and it will happen for real! They know that Alhamdulillah we will never go in these acts what they are doing, there is always like a competition between them and us, although we read muawwazatein, aayatul kursi, aamanar rasulu, sure kahf for protective purpose. After we meet them, at least one of us suffers severe headache, and bone pains and back pain like our bones are crushing and muscles are twisting. It happens for the entire night. The next day we will be normal. Also, they don't have manners, before they come to our home (without informing us), any member of our family opens the door for any work, they just come into the room and sit down. They sometimes give us a warning that "see that one hadn't obeyed us and now he is suffering from this disease" they always warn us like that, before they arrive or after they go from our home, my parents always fight (very harshly).  I ask you for a powerful dua from the Quran and hadith which resist's all the bad powers from the hypocrites and their supernatural attackings.
