After תשמיש she immediately found דם but he may enter the היכל and burn incense.
- Shamai permits this even if he completed the ביאה.
- This follows R. Akiva that the man is טמא
- If there was no קרי Shamai only forbids her from now on.
- She did not have time to check.
- She did not have a cloth available.
If after ביאה she sees a stain on her clothes the husband is:
- טמא but everyone agrees only from now on because כתמים are דרבנן
- טמא and there is a מחלוקת whether this is retroactive or only from now on.
- טהור because כתמים are דרבנן.
- טמא because כתמים are דאורייתא
- מחלוקת A&C
The husband came home and the time for his wife's cycle has arrived:
- Since וסתות are דאורייתא she is forbidden to him.
- Since וסתות are דרבנן she is permitted.
- מחלוקת A&B.
- Even if she has no וסת since he returned within 30 days of last bleeding she is forbidden.
- She is always permitteHed because the Mishnah says she always has a חזקת היתר.
The husband who came home from a journey can assume that his wife went to Mikveh:
- Even if he knows she had a period he can assume she immersed.
- If he came home 7 days after her period she is permitted.
- If her וסת depends on her jumping he can assume she jumped.
- Because וסתות דרבנן we are lenient.
- If he is not sure if she had a period he can assume that she went to Mikveh.
A חבר died and left a store full of fruit that was plucked today:
- The חבר certainly separated תרומות ומעשרות before he died.
- The fruit might not have been liable מדאורייתא.
- Nowadays תרומה is דרבנן so we are lenient.
- מחלוקת A&B
- It is permitted to cheat and say that the fruit came from חוץ לארץ.
A Cohen leaned over the pit where there was a dead baby but they said he was טהור.
- It was not certainly a baby but anyway the weasels and polecats might have dragged it away.
- The rule is that a ספק overrules a ודאי.
- Nowadays it is not certain that כהנים are really כהנים.
- The Cohen was not learned.
- We are lenient because the Cohen wanted to bring קרבנות.
