Suppose I enter a kosher bakery and want to purchase some food item from the shelves. Can I pick that thing up by my hands for purchase?
My reason is that the laws of Kashrut are very very strict, and I do not want to pollute the kosher items kept in the shelves, but I want to purchase as those things are clean and Halal for muslims to eat or consume, but I also do not want to violate any laws of kosher.
