What's the Halachah? Bamidbar - Devarim

May someone who attended a shiur for years switch to another shiur from which he will gain more if doing so will offend the first maggid shiur?

• When must a visitor to the Kosel perform kriah? May someone who wishes to avoid performing kriah delay visiting the Kosel until Friday afternoon?
• Is it acceptable for a home or yeshivah to have a single microwave that will be used for both milchig and fleishig food if the food will always be covered well?
• If a sofer checked a pair of tefillin and declared them kosher but it was later discovered that he made a mistake, is the person who wore the tefillin considered to have fulfilled the mitzvah?

Rav Zev Smith, a renowned maggid shiur for Irgun Shiurei Torah, Dirshu, and other prominent organizations, and Rabbi Dovid Kaiser, an author of Torah works and a maggid shiur in halachah, have teamed up once again to explore dozens of topics in halachah.

Each of these topics, carefully chosen for their importance, relevance, and interest, are discussed clearly and comprehensively, so that the answers to the above questions, and dozens more, become crystalized for the reader. The second volume of the What’s the Halachah? On the Parshah series, this book has been arranged according to the parshiyos hashavuah of Sefer Bamidbar and Sefer Devarim. As with the first volume, each chapter is introduced with a captivating dvar Torah that connects the chapter’s halachah topic to that week’s parshah.

What’s the Halachah? On the Parshah does more than just teach you practical halachah; it opens before you the vastness and beauty of the world of halachah!
