What If... makes a wonderful addition to our Shabbos table. Rav Yitzchok Zilberstein shlita is a noted rav and posek, as well as a son-in-law of Rav Elyashiv zt'l. What If... presents hundreds of halachic questions and answers in the order of the weekly parashah, making it the perfect starting point for fascinating Torah conversations.

The questions are short, and each includes a practical, real-world scenario. The answers, too, are concise, and though they contain a world of Torah knowledge, they are easy to follow.

• A man jokingly tells his friend to microwave an esrog to make it ripen quickly - who is responsible for the damage?
• A surgeon learns a new technique from a presentation, without paying the entrance fee. May he use that technique, or is it stealing?
• A mother doesn't want to reveal her child's illness, thus keeping people from praying for him. Is that permitted?

Challenge your family or guests with these thought-provoking halachic questions, and watch the energy around the table begin to surge. This is Torah conversation at its best.
