However, it is not permissible to divide what is required for one individual between two recipients. If you have a Muslim or non-Muslim (dhimmi) servant, you must give Zakat al-Fitr on their behalf. If a child is born to you on the Day of Eid al-Fitr before noon, it is recommended to pay Zakat al-Fitr for them. If they are born after noon, no Zakat al-Fitr is due on them. Similarly, if a person converts to Islam before or after noon, Zakat al-Fitr is recommended in both cases, as an act of virtue and preference. As for the obligatory Zakat al-Fitr, it is only incumbent on those who have completed the month (i.e., were present during Month of Ramadan).
