594/767 عن ابن عباس: "القوس: أمانٌ لأهل الأرض من الغرق، المجرة: باب السماء الذي تنشق منه".
It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them): The rainbow is a protection (safeguard) for the people of the earth from drowning, and the Milky Way is the gate of the sky from where it emerges.
