huhu... most of people will think it's hard to find clean soil because lot of people think that the soil itself is a dirt... hehehe... well.. it's easy, you can find mud soil anywhere as long as it is clean from other secondary dirt such as blood, or human/ animal waste <-- this one not so sure since a lot of people (especially those construction worker from pakistani or bangladeshi like to pee everywhere) huhuhu... (i'm so sorry to say that to our pakistani/bangladeshi bro & sis), well this is based on my general observation... not to say all... but a part of them... back to the soil story... as long as the soil is not contaminated with dirt or in malay we call it najis (mostly from organic lives).. it should be fine...
