What is the ruling on giving the monetary value instead of a sa' of food for zakat al-fitr?

The Shaykh : This person says that a sa' of dates and a sa' of barley, if you grind it. There are no mills, in any case, I know that dates are not ground. Are dates ground, people? Barley? Wheat, yes. Well done. This person says that a sa' of food, whether it is barley, wheat, or rice, is not needed. The poor person does not need it; he only needs clothing for his children, is that right? So why don't we give the value?
I say that we are commanded to follow the Shari'ah, not to follow the contract. And we do not prevent you from giving a sa' of food and adding dirhams to it so that they can eat and wear clothes. We say, may Allah reward you with good, add dirhams to this sa', whether you can or cannot. Well, if you wrap up the dates, if you give them the dates, if you like to eat them, eat them, otherwise sell them. Praise be to Allah, it never goes against half the price or a quarter of the price, it is never in it.
