Niddah 7:5-8:1

Niddah 7:5

Samaritans are believed if they claim to have buried or not to have buried miscarriages in a certain location. They are believed regarding whether or not an animal has delivered a firstborn. They are believed about grave markings but not about branches overhanging or stones surrounding a grave, nor about a beis hapras (a field in which a grave was plowed). The general rule is that Samaritans are not believed in any matter about which they are suspected.

Niddah 8:1

If a woman sees a bloodstain on her body opposite her genitalia, she is ritually unclean; if it is not opposite her genitalia, she is clean. If she finds a bloodstain on her heel or on the tip of her big toe, she’s unclean. On the inside of her leg or foot, she’s unclean; on the outside, she’s clean. On the sides in front or in back, she’s clean. If she saw the bloodstain on her shirt from the belt down, she’s ritually unclean; from the belt up, she’s clean. If she saw the bloodstain on her sleeve, then if the sleeve reaches her genitalia, she’s unclean; if not, she’s clean. If she takes the garment off and covers herself with it at night, she’s unclean regardless of where the bloodstain is found because the garment moves around. The same is true of a nightcap.
