Dear Rabbi, It's me again with another question. I have a Torah (Bangla Edition by Biblecal Socity of Bangladesh). There I have seen that Prophet Luth left the country to avoid punishment from Allah which fell on his nation. And he left with his two daughters. After sometime daughters made a sin, Both of them had sex with Prophet Luth and become pregnant (At first make him drunk so that he cant remember this incident). One gave birth a boy and she named him Moab and Later Amman. Will you please explain me about this incident. As fur as I know Prophets are the best man of their time. So is it possible to make such sin by them. And I know Jews are not allowed to have sex with woman other than one's wife.

Dear Rabbi Lauffer,Thank you for your response. I see from your answer that one is paid back for [as much as you want to spend for] the mitzvos which the Torah says that we're paid back for, which is what I wanted to know. But you added that not all mitzvos are in this category. I am not questioning your psak, but I would like to mention what spurred my question. I was reading a book called, "Trust Me!", by Rabbi Eliezer Parkoff. On page 436, he writes the following:"The Mishnah Berurah (in Be'ur Halachah) cautions that this statement refers only to Torah study and Shabbos and Yom Tov expenses;* regular weekday expenses are not included.*The Shita Mekubbetzes (on Beitzah 16a), quoting the Ritva, states that the Gemara is not only referring to these three things. Rather, it means any mitzvah. The reason it mentions these three things specifically is because they are quite common. Moreover, the Mishnah Berurah seems to rule according to this understanding, for in Orach Chaim 242, note 4, we read: "...for the needs of a Shabbos meal or seudas mitzvah." "Now, obviously, you and Rabbi Parkoff can disagree on how to interpret this halachah; I just wanted to know if that was, indeed, the case. Maybe not everyone agrees with the Shita Mekubbetzes. I don't know; I'm not a posek. Would you please clarify whether this is a machlokes, or not?Thanks,Yaakov Laska

Dear Rabbi, It's me again with another question. I have a Torah (Bangla Edition by Biblecal Socity of Bangladesh). There I have seen that Prophet Luth left the country to avoid punishment from Allah which fell on his nation. And he left with his two daughters. After sometime daughters made a sin, Both of them had sex with Prophet Luth and become pregnant (At first make him drunk so that he cant remember this incident). One gave birth a boy and she named him Moab and Later Amman. Will you please explain me about this incident. As fur as I know Prophets are the best man of their time. So is it possible to make such sin by them. And I know Jews are not allowed to have sex with woman other than one's wife.

What is the significance of placing a stone on a grave when you vist the cemetery. Thank you

If a person has a choice between two ways of doing a mitvah, but one is more expensive, and more convinient ("roll-out" schach, or Chanukah glasses with pre-filled oil), does this also go in the category of Yom Tov expenses, vis a vis being paid back Min Hashomayim?
