Say, “You disbelieve in the One who created the earth in two days,* and you set up idols to rank with Him, though He is Lord of the universe.”
قُل أَئِنَّكُم لَتَكفُرونَ بِالَّذى خَلَقَ الأَرضَ فى يَومَينِ وَتَجعَلونَ لَهُ أَندادًا ذٰلِكَ رَبُّ العٰلَمينَ
qul a’innakum latakfuroona billazee khalaqal arda fee yawmaini wa taj’aloona lahooo andaadaa; zaalika Rabbul ‘aalameen
*41:9-10 The “days” of creation represent a yardstick. Thus, the physical universe was created in two days, while the calculation of provisions for all the creatures on earth required four. This also teaches us that there is life only on this planet Earth.
