Hospital samples and children’s urine in swimming pools

The questioner:
But let’s take a call from our brother Abu Rashid from al-Madinah al-Munawwarah. Go ahead, Abu Rashid. Peace be upon you. And upon you be peace. Abu Rashid, turn the television down a little. Turn the television down. Okay, my dear. Go ahead, my dear. My dear, I have two questions. The first question: We notice that in clinics and hospitals, they take samples from patients and write the patient’s name on them, like Abdullah or Abdulaziz, and then when they are done with these samples, they throw them in dirty places. And you know, these are urine and feces and such. The second question: There is a swimming pool in a hall at a rest house where they slaughter goats, and both big and small children urinate in it and such. I don’t know what the ruling on this is? Okay. May Allah bless you. Thank you. Go ahead, Shaykh. Some hospitals take samples from patients, and they throw them away after taking these samples?

The Shaykh:
No, what’s wrong with throwing them away after they are done with the samples? Is it urine or feces that is thrown away?

The questioner:
Okay, he says: Some children in swimming pools, if they are older, may urinate in these pools, and some people come out and are in a state of wudu’ (ablution), so what is the ruling on that?

The Shaykh:
If the water is a small amount, it becomes ritually impure with urine and feces. But if the water is a large amount and no smell, color, or taste appears in it, then it is purifying, praise be to Allah. Yes.
