Is zakat obligatory on money saved for two brothers when it reaches the nisab, and what is the nisab in UAE dirhams, and must zakat also be paid from it in UAE dirhams?

Saved money is subject to zakat if it reaches the nisab and a full year has passed on it, and it is owned by a specific Muslim. If the saved money belongs to the two brothers and the share of each of them reaches the nisab, then the father must pay its zakat from their money. The nisab for zakat is equivalent to 85 grams of gold or 595 grams of silver, and the amount of zakat to be paid is one-quarter of one-tenth (2.5%). It is preferable to invest the money so that it is not affected by the payment of zakat.
