Is it permissible to divide the Zakat amount paid to orphans into monthly installments throughout the year?

It is permissible to give Zakat in installments to poor orphans if it is advanced before its due time and before the completion of the hawl (one lunar year). However, paying Zakat in installments after it has become due is not permissible, because it leads to delaying the disbursement of Zakat. The fundamental principle is that Zakat must be disbursed immediately after it becomes due.
