Surah Al-Anbya, Ayah 19

Creation was made with Justice and Wisdom

Allah tells us that He created the heavens and the earth in truth, i.e. with justice.

لِيَجْزِىَ الَّذِينَ أَسَاءُواْ بِمَا عَمِلُواْ وَيِجْزِى الَّذِينَ أَحْسَنُواْ بِالْحُسْنَى

(that He may requite those who do evil with that which they have done, and reward those who do good, with what is best.) 53:31. He did not create all that in vain or for (mere) play:

وَمَا خَلَقْنَا السَّمَآءَ وَالاٌّرْضَ وَمَا بَيْنَهُمَا بَـطِلاً ذَلِكَ ظَنُّ الَّذِينَ كَفَرُواْ فَوَيْلٌ لِّلَّذِينَ كَفَرُواْ مِنَ النَّارِ

(And We created not the heaven and the earth and all that is between them without purpose! That is the consideration of those who disbelieve! Then woe to those who disbelieve from the Fire!) 38:27

وَمَنْ عِندَهُ لَا يَسْتَكْبِرُ‌ونَ عَنْ عِبَادَتِهِ وَلَا يَسْتَحْسِرُ‌ونَ (And those who are near Him are not arrogant against His worship, nor are they sluggish. - 21:19) It means that Allah's servants who are with Him i.e. angels pray to Him all the time without ceasing. So, if the humans do not pray to Him, it will not make any difference to Him, but they themselves will be the losers. It is human nature to judge others by applying one's own situation to them. Hence there are two possibilities preventing a person from offering acts of worship ceaselessly. One, that he regards it below his dignity to bow down before any one and therefore does not pray to Allah Ta` ala. Secondly, it is physically not possible for a man to worship without a break because he needs to rest in between. In view of these two human constraints, it is explained towards the end of the verse that the angels are free from these compulsions. They do not regard it below their dignity to worship Allah constantly nor do they get tired or need any rest or sleep.

Those who are not serious about the divine call, consider the present world as a plaything of God which has no purpose except temporal entertainment. But judging by the immense wisdom and meaningfulness underlying the working of the present world, it would appear to be impossible that the Creator of this world could be a being who has created it merely for the sake of diversion. In the present world, there is the special creation of God, namely, human beings, who by their very nature, have the ability to distinguish truth from falsehood. The existence in the world of such creatures, who can use their discretion and decide upon one path as that of truth and another as that of untruth, coupled with the frequent struggle between Truth and untruth, are all indications of the fact that a time is going to come when it will finally be clear as to what is really Truth and what is Untruth. And whoever sides with the Truth will attain success and whoever does not will be doomed to failure.
