Is it permissible to give Zakat al-Fitr to my divorced aunt who does not work, owns half a donum of land, and has married daughters, or should it be given to another poor person?

Scholars have differed regarding the rightful recipients of Zakat (definition) al-Fitr, and the preponderant opinion is that it should be given exclusively to the poor and the needy. It is permissible to give Zakat on wealth (Zakat al-Mal) and Zakat al-Fitr to poor relatives, and this is better than giving it to those who are not relatives, provided that the giver is not obligated to financially support this relative. If your aunt is poor, meaning that the value of her land is insufficient for her annual expenses, or if she is unable to sell it, or if her income from investing the land does not cover her usual expenses, then she is eligible to receive Zakat.
