There are many seforim stores that have a minyan for Mincha in the store. If someone were to use a siddur from the store in order to daven with that minyan in a way that there's no perceived damage on the siddur, and nowhere is there a written policy to not use the siddurim for Mincha purposes.



  1. Can a siddur be used Lechatchila?


  2. Can the owner compel him to buy it now?

No. One who borrows an item without permission from the owner is conidered a gazlan (שואל שלא מדעת גזלן), and like all cases of stealing, must return the item (והשיב את הגזילה אשר גזל). He is not required to purchase the item or to pay for the usage. If any damage was caused, however, he must pay the full value of the product, not just the amount the item depreciated through the damage.

  • I would add two things - 1. The books ARE for sale and once someone raises them for his USE he acquires them 2. Your rule probably only applies to occasional use, but not repetitive. 3.

  • @AlBerko 1. Not necessarily. Only if he takes it with the intention to acquire it; what if he takes it with the intention to use and return?
