Due to a lot of confusing answers I would request for a clear answer please to my question: Is forex trading halal from an Islamic account which is swap-free?
Let see definition of Forex from Wikipedia:
The foreign exchange market (forex, FX, or currency market) is a global decentralized market for the trading of currencies. This includes all aspects of buying, selling and exchanging currencies at current or determined prices.
If it's for trading it's permissible for Islam. Generally Muslims see Forex halal supporting with this hadith:(I am getting this from islamqa.info)
“Gold for gold, silver for silver, wheat for wheat, barley for barley, dates for dates, salt for salt, like for like, same for same, hand to hand. If the types are different then sell however you like, so long as it is hand to hand.” Narrated by Muslim, 1587.
However, buying stocks from companies which are selling or providing non-Islamic products is not permissible. Like buying stocks from alcoholic beverage seller:
"The Messenger of Allah (Peace be upon him) cursed ten involved in wine: The one who presses it, the one who has it pressed, its drinker, its carrier, and the one it is carried to, its server, its seller, the consumption of its price, the one who purchases it and the one it was purchased for."
Jami` at-Tirmidhi Book 12 Hadith 1295
