What is the ruling on buying and selling international currencies? What is the ruling on trading in international stock markets through a financial intermediary using the margin system, and what are the rules governing that? Is it permissible to buy and sell shares of foreign industrial companies that engage in lending and borrowing with interest?
If the transactions involve dealing with usurious banks, or a breach of currency exchange regulations, or gharar (excessive uncertainty) and jahalah (ignorance), or Riba (usury), or aiding in it, or other Sharia violations, then they are unlawful (haram). However, if they are free from these matters, then they are permissible ( جائزة).
