Is Zakat obligatory on money allocated for travel tickets and study, knowing that it has reached the nisab, and the payment of these amounts has been delayed due to the current circumstances?

There is no obligation to combine the wife's wealth with that of her husband or children; each has an independent financial standing. Zakat (definition) becomes obligatory for whoever's wealth reaches the nisab (definition) and a full lunar year (hawl) passes over it, and the commingling of money does not affect the obligation of zakat. Saved money is subject to zakat if it is not spent during the year. Newly acquired money (such as installments) is not subject to zakat on each installment until its hawl passes, according to the majority of scholars. However, the Hanafis combine it with the principal amount and zakat is paid on it accordingly. Whoever has a debt deducts it from the wealth subject to zakat, according to the majority of scholars. If a full year passes over the saved money and it reaches the nisab, its zakat becomes obligatory, even if it is for the purpose of buying tickets or other things. If a full year has not passed over it or it has not reached the nisab, there is no zakat. The outstanding debt is deducted from the wealth subject to zakat, according to the majority of scholars.
