According to the Shariah, Fitra becomes incumbent when the new moon of Shawwal is sighted. This is known as Zakat of Fitra, which is Wajib on every Baligh person.
If you have a guest with you, who has arrived at your house before sunset on the eve of Eid al-Fitr, then his/her Fitra is WAJIB upon you.
As per law 1999 of Ayatullah Seestani's Islamic laws: “At the time of sunset on Eid al-Fitr, whoever is adult and sane and is neither unconscious, nor poor, or the slave of another, he should give, on his own behalf as well as on behalf of all those who are his dependents, about three kilos per head of wheat or barley or dates or raisins or rice of millet etc. It is also sufficient if he pays the price of one of these items in case.”
