On The Rainbow
In the Abrahamic traditions, the rainbow serves as a divine sign of a covenant following a cataclysmic flood, marking a shift from judgment to preservation. While Judaism and Christianity explicitly identify the bow as a memorial of God's promise never to destroy the earth by water again, Islamic exegesis focuses on the survival of the prophet Nuh and his followers as the fulfillment of divine mercy, with the rainbow often interpreted in later tradition as a sign of God's power rather than a contractual stipulation. Scholars note that the Genesis narrative uniquely personifies the bow as a weapon hung up by God, a motif absent in the Qur'anic account which emphasizes the immediate salvation of the believers.

What every account tells.
- iA divine covenant is established following a great flood.
- iiThe sky or a celestial phenomenon serves as the sign of this covenant.
- iiiThe sign functions as a reminder of divine mercy and restraint.
- ivThe narrative involves a righteous figure (Noah/Nuh) who survives the deluge.
How each tradition tells it.
The text explicitly frames the bow as a sign of the covenant between God and every living creature, emphasizing the universal scope of the promise. The bow is described as a weapon of war that God has placed in the clouds to signify that He will no longer use it against the earth.
While retaining the Noahic covenant, the New Testament introduces a distinct apocalyptic image where a rainbow encircles the throne of God, symbolizing divine presence and judgment in the end times. This shifts the motif from a historical promise of non-destruction to an eschatological symbol of God's sovereignty.
The Qur'anic narrative focuses on the command to build the ark and the subsequent salvation of the believers, without an explicit verse establishing the rainbow as a covenant sign in the same legalistic manner as Genesis. Traditional tafsir often links the rainbow to God's attributes of power and mercy, but the text itself emphasizes the deliverance of Nuh's community as the primary outcome of the flood.
