Q: I have relatives who were not on the straight path and ignorant about Islam and now I want to help them to do their zakaat, so I have a number of questions.
1. How do we calculate a date for Zakaat? They're both above the Nisaab. Do we calculate via picking a new date or by estimating when they last went above the threshold for zakaat?
2. How should the zakaat of the past years be calculated? From what starting point?
3. If one has a debt, but has money that is above the threshold amount, must he pay zakaat? But if the debt is paid then he will be below zakaat, will he be obligated to pay zakaat still if he doesn't pay the debt for a year?
4. How is Zakaatul Fitr paid and is it Fardh?
5. Is zakaat due on inheritance?
