The purpose of this paper is to ascertain the prevailing Sharīʻah issues in Islamic capital markets, particularly ṣukūk. Common features of conventional bonds are replicated in ṣukūk via late penalty payment upon default, trading of debt-based ṣukūk, purchase undertaking in equity-based structures and ownership status in asset-based transactions. These features pose Sharīʻah concerns and are discussed in the paper from the perspective of current practices and views of scholars by compiling various references that reveal the diversity of the Sharīʻah. The paper does not claim to provide solutions to the issues of debate; rather it engages in providing ananalysis of these Sharīʻah issues. The four issues covered are certainly not exhaustive; more issuesare expected to creep up as ṣukūk structures continue to evolve over time. The paper provides value by shedding light upon the discussed issues and it also highlights the need for a balance between growing the ṣukūk market and upholding Sharīʻah in all aspects when structuring ṣukūk.
