Taweez

Q: A mufti gave me a taweez to burn with numbers written on it. What do you say in this matter?

Performing only 8 rakaats taraweeh in a musjid nearby

Q: My question is that my father cannot pray 20 rakaats taraweeh in mosque nearby because its too quick and have to travel by car. He likes to pray in a mosque next to our house which performs 8 rakaats. I have a problem because prophet Muhammad (Sallallahu Alayhi Wasallam) and him companions prayed 20. I want to go to the other mosque so my dad then takes me in his car but he has problems. So what should I do? Leave the 20 rakaats taraweeh or just force my dad to take me or do something else?
