Taking Advantage of Another’s Financial Situation…
It is reported that doing business with someone who is compelled (whether to buy or to sell) is forbidden.
Ali Ibn Talib RA delivered a speech saying, “A miserly time will come when the rich will stingily hold on to what they have, though they have been prohibited from doing so. Allah, the Almighty, says:
‘and do not forget ‘fadl’ (kindness, liberty) between yourselves.’ [al-Baqarah, 237].
Yet people do business (unjustly) with those who are forced to buy or sell due to need, though the Prophet SAWS forbade doing business with one in such circumstances.” (Abu Dawud)
