Is zakat obligatory on money that has been held for a full year for the two brothers residing outside the country, given that there is a common debt owed by them and their brothers inside the country?

Partnership does not affect zakat (definition); rather, each partner must pay the zakat on their wealth if it reaches the nisab (definition) and a year has passed over it. Zakat includes business profits, cash, and other trade goods. The partner's share of the company's debts is deducted from the wealth on which zakat is due. What remains after deducting the debt is subject to zakat, because, according to the majority of scholars, debt prevents the obligation of zakat on hidden wealth. The nisab for banknotes is approximately equivalent to 85 grams of gold.
