Fitrana (Sadaqatul-fitr)
Sadaqah al-Fitr is an emphasized Sunnah (which according to many is compulsory). This becomes due before Eid al Fitr Salah, although it is preferable to give it a few days before Eid so that the poor actually receive it and are able to spend it on Eid day.
If one does not give the Sadaqah al-Fitr, it will remain due no matter how much time passes after Eid.
If a person possesses the value of Nisab beyond his basic needs then they must give Sadaqah al-fitr.
The amount that must be given is equal to 1.6 kg of wheat or 3.2 kg of barley or it’s like. This does not mean that a person must distribute wheat or barley, one may give its equivalent value.
Fitrana can be known as Zakat ul Fitr or Sadaqatul-Fitr
