Selling gold on credit is prohibited if it is exchanged for something in which delay is not permissible. For instance, selling gold on credit in exchange for dirhams (silver currency) is haram (forbidden) and impermissible.
However, if gold is sold on credit in exchange for something that can be legally delayed in payment, then there is no harm in it. For example, selling gold jewelry in exchange for clothes, tools, vehicles, or similar items is permissible.
