Zakaat on loans that are owed to one
Q:
1. I have 1500 dollar cash with myself and my sister borrowed 500 euros from me 3 years before and my brother borrowed 500 dollars from me 3 years before. My husband borrowed 600 dollars from me 1 year before. So how should I calculate zakat for this money?
2. My husband has 15000 dollars in his account and almost 10000 dollars at home with his mother but the money he has at home is saving money from his salary every month he saves the money from his salary. What is the procedure for salary zakaat?
