Islamic banking operates according to Islamic religious principles, which prohibit interest and encourage profit and loss sharing. Some major modes of Islamic banking and financing include murabaha, ijara, ijara-wal-iqtina, istisna, bai muajjal, mudarabah, musharakah, and bai salam. Islamic banking first emerged in Egypt and Pakistan in the 1960s-1970s and has since grown globally. In Pakistan, Islamic banking has a long history and the government has taken steps since the 1980s to gradually Islamize the conventional banking system.
