Is it permissible to use a scheme that involves staging a scene with a secretary pretending she wants to buy a property at a higher price (35,000) to push the real buyer to raise his price from 22,000 to 32,000?

“Najsh” (to outbid another with no intention of buying) is forbidden by Islamic law because it involves deceiving and defrauding the buyer through this prohibited trick, and consuming people's wealth unjustly. This is based on Allah’s saying: "And do not consume your properties among yourselves unjustly" (Quran 2:188), and the Prophet's (peace be upon him) saying: "Do not envy one another; do not hate one another; do not spy on one another; do not pry into one another’s affairs; and do not practice Najsh against one another. Be, O servants of Allah, brethren." Najsh is defined as increasing the price of a commodity by one who does not intend to buy it.
