Sadaqah al Fitr and Zakat are similar in the sense that the eligible recipients of Zakat are also eligible to receive Sadaqah al Fitr. Essentially, it is permissible to give Sadaqah al Fitr to all categories of people who are eligible to receive Zakat according to Shariah. Simultaneously, all categories of people who are not eligible to receive Zakat according to Shariah cannot be given Sadaqah al Fitr.
