One would think that God’s final revelation to mankind, the Quran, would be a truly elevated and inspiring work. Instead, we find that it often lends itself to subjects that are quite base. There may have been a reason for this and, as with any historical topic, it helps to understand the context.
To give you an idea of the abject backwardness of Pre-Islamic Arabia, the practice of having carnal relations with one’s own flesh-and-blood seems to have been problematic enough to require a PSA from God. The Almighty actually dedicates a full verse in the Quran (verse 4:23) explicitly prohibiting the believers from marrying their mothers, daughters and sisters. Apparently, back in the “good ol’-days” bedding one’s own mother was something one had to be taught not to do!
