Ramadhaan & Fasting

Fidyah

Q: I like to ask you about fidyah. 

1. If you can't fast in Ramadan because of ill health, do you need to give fidyah for 30 days? 

2. Do you need to give fidyah to one person or more than one persons? 

3. Can I give fidyah to a charity organisation then they may distribute it?
