Once again the argument turns to Monotheism and polytheism, which are the most important matter in Islam to discourse about:ِ
``To Allah belongs whoever is in the earth.''
In other word, all the creatures are subject to God; whatever they be and whoever they are, Allah has created them, and He owns them. If therefore any partners from among His creatures are set up and associated with Him, they are merely false compeers invented by imaginations and forged by conjectures. No reason can be brought to prove such false and imaginary ideas.
In the second verse above, night and day are introduced as two signs of God's infinite mercy and unrejectable Monotheism:ِ
``He is who made for you the night to rest and repose, and made the day visible for your activities.''
If the alternation of day and night stopped, who can move the earth round about once again and change a night for day!? We should know that our life is linked with the alternation of our rest and activity, which depends upon the alternation of night and day. In the night when everything is calm and quiet, we may repose and have a rest; and in the day when everything is visible, there is a chance for our activity and work. Here an ear is wanted to hear and a heart to reflect.
