light and dark
Hu has made the light contrary to the darkness, the wetness to the dryness, the harshness to the softness, the coldness to the heat. He combines their transgressing and separates their closeness. The separation among things is evidence of the existence of the One Who causes separation in them and their combinations is evidence of the existence of the One Who combines them. It is just as Allah has said, “We have created everything in pairs so that perhaps you may take heed (51:49).” (Imam Ali (AS) as narrated by Imam Jafer Sadeq (AS) Al-Kafi H 349, Ch. 22, h 4)
