The command to observe Islamic rulings

A Muslim should submit with acceptance and contentment to the rulings of Shariah, even if the reason for the obligation or prohibition is not known. However, the reason for some prohibitions is apparent, such as the prohibition of interest (usury). The reason for its prohibition is that it takes advantage of the neediness of the poor, the burden of debt doubles on them, and as a result, enmity and hatred arise. Due to becoming addicted to interest, work is abandoned, reliance is placed on interest-based profits, and efforts to seek lawful sustenance are forsaken. Besides this, there are many other major harms and defects as well.
