The amount of the sa' in zakat al-fitr in kilograms

Question:
Your Eminence! This is a listener from Sudan who has a set of questions. The listener did not mention his name in this message. He says: What is the amount of the sa' in zakat al-fitr in kilograms in our day? And does zakat al-fitr become waived if one is unable to pay it? May Allah reward you with good.

Answer:
The amount of zakat al-fitr is now, by our sa', approximately three kilograms; because five pounds is like the sa' of the Prophet (peace and blessings be upon him), which is four full, medium-sized hands, as mentioned in the Qamus and elsewhere. If one fills his hands four times, and they are of medium size, and he fills them completely, that is one mudd, and the four hands make a sa'. In kilograms, it is approximately three kilograms, slightly more than three kilograms. So if one gives three kilograms, he has exercised caution and given a complete sa' for the fitrah. Yes.

The presenter : May Allah reward you with good.
