Answer
(Fatwa: 1191/1191=M/1429)
If you have been possessing 19 tola gold since 2002 till date, then you should calculate fortieth part (2.5%) of 19 tolas, and you will have to pay this fortieth part in zakah for each year. If you want to give zakah in cash, get its market price and pay fortieth part (2.5%) of the money as Zakah for each year. Also, you should calculate zakah of every year separately form 2002 to 2008, and then deduct ten thousand rupees which you have paid already and pay zakah of the rest of money.
