Ruling on a small amount of rice falling into the drains when washing it

Question:
What is your guidance for one who washes rice and pours its water into the drains? Is this permissible, or not?

Answer:
There is nothing wrong with pouring it into the drains if what is in it is rice that can be used, a few grains, or something that cannot be used. However, if there are grains, he should take the grains and pour only the dirty water. As for the grains of wheat or rice, he should not throw them into the drains. But if one or two grains slip through unintentionally, it does not harm him.
