My question is about converting currency. Can I convert my money to USD (i.e. American dollars) and put it in the bank and convert it back to rupees when the value of USD increases? Please tell me through the Quran and Hadith whether this is Halal or Haram.
The method inquired about in the question (i.e. converting rupees into dollars and putting it in the bank, then converting it back from dollars to rupees when taking it out) is permissible as per Shari’ah.
