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?

Q: I am listening to a lecture here at work and just determined or realised that there is a difference between zakaat, fitrah and sadaqah and I realised that I don't think I pay zakat?
