4. Rain Water

40. A Najis object will become Pak if rain falls on it once provided that it is not essential Nejasat. And in objects like carpet and cloths, it is not necessary to wring, but the rain must be sufficient so that people say that it is raining, and several drops of rain is not enough.

41. If rain water falls on essential Nejasat and splashes elsewhere, and if the essential Nejasat is not carried with it and it does not acquire the smell, color, or taste of Nejasat, then the water is Pak. So, if it rains on blood and then splashes, and particles of blood are seen in the water, or it acquires the smell, color or taste of blood, it is Najis.

42. If there is essential Nejasat on the roof of a building, and water flows down from the roof after contacting the Najis object, it will be deemed Pak as long as the rain continues. But if it continues to flow down the same way after contacting the Najis object, after the rain has stopped, that water will be Najis.

43. The Najis earth or ground on which rain falls becomes Pak; and if it begins flowing on the ground, and while it is still raining it reaches a Najis place under the roof, it makes that place Pak as well.

44. If rain water falls on Najis dust or sand, soaking it thoroughly, it becomes Pak.

45. If rain water collects at a place, even if its quantity is less than a Kurr, and a Najis thing is washed in it while it is raining, it becomes Pak provided that it does not assume the smell, color or taste of the Najis.

46. If it rains on a pure carpet, which is spread over a Najis ground, and if the water seeps onto the Najis ground while rain continues, the carpet does not become Najis. In fact, the ground also will become Pak.

47. If the rain water or some other water is collected in a hole and it is less than Kurr, and if Nejasat reaches it after the rain fall, it will be Najis.
