Question
What is the ruling if I post an image from the Amazon website showing the price of a book there, and the price of the book with us? Does this fall under the category of selling to a brother, given that the price of the book there is double the price of the book I have?
Answer
I say, and with God's guidance: The prohibition of selling on the sale of one's brother, in the case where there is an agreement between the seller and the buyer, and a third party intervenes in the offer, is disliked. What you have mentioned is different, and God knows best.
