How do we respond to non-Muslims who ask us how could Allah say that He has made this earth and universe in 6 days when the concept of days is linked to the earth itself?
Our concept of day and night with us human beings, is not necessarily the same concept of day with Allah who Created every thing including the time before creating the earth and sky. Time was created before earth and sky and that time had got its day which is different from our day.
'Wassalam.
