﴿ أَوَلَمْ يَسِيرُوا۟ فِى ٱلْأَرْضِ فَيَنظُرُوا۟ كَيْفَ كَانَ عَٰقِبَةُ ٱلَّذِينَ مِن قَبْلِهِمْ ۚ كَانُوٓا۟ أَشَدَّ مِنْهُمْ قُوَّةًۭ وَأَثَارُوا۟ ٱلْأَرْضَ وَعَمَرُوهَآ أَكْثَرَ مِمَّا عَمَرُوهَا وَجَآءَتْهُمْ رُسُلُهُم بِٱلْبَيِّنَٰتِ ۖ فَمَا كَانَ ٱللَّهُ لِيَظْلِمَهُمْ وَلَٰكِن كَانُوٓا۟ أَنفُسَهُمْ يَظْلِمُونَ ﴾

“Have they, then, never journeyed about the earth and beheld what happened in the end to those [deniers of the truth] who lived before their time? Greater were they in power than they are; and they left a stronger impact on the earth, and built it up even better than these [are doing]; and to them [too] came their apostles with all evidence of the truth: and so, [when they rejected the truth and thereupon perished,] it was not God who wronged them, but it was they who had wronged themselves.”

Constant remembrance (through prayer, etc.) and deep contemplation lead a man towards finding God. It is by profound thought that a man finds God. In the present world, God has scattered His signs everywhere—in the human environment, in the surrounding universe and also in the teachings of the Prophet. Those who give serious consideration to these signs of God will find God. Argument in favour of God is God’s representative on earth. If rightful argument is presented to a man and he ignores it, it is as if he has ignored God Himself. For such people there is nothing before God except eternal deprivation.
