O you who believe! many of the priests and the monks certainly swallow the wealth of people wrongfully and turn (them) away from the way of Allah; and those who hoard gold and silver and do not spend it in the way of Allah, convey to them the news of a painful punishment,
There are many so called religious leaders who do not guide people towards the Quran and the Sunnah of Prophet Muhammed (PBH). They take money from them in the name of Islam but put it to personal use. This wealth which they had sinfully acquired and hoarded will be heated in the fire of hell and with it their bodies will be heated at different places as punishment. This may also refer to people who hoard money and do not spend it in the way of Allah.
