١٢٣" Allah's statement,

إِن يَشَأْ يُذْهِبْكُمْ أَيُّهَا النَّاسُ وَيَأْتِ بِأخَرِينَ وَكَانَ اللّهُ عَلَى ذَلِكَ قَدِيرًا
 
 

If He wills, He can take you away, O people, and bring others. And Allah is Ever All-Potent over that.

means, He is able to take you away and replace you with other people if you disobey Him.

In a similar <b>Ayah</b>, Allah said,

الْفُقَرَاءُ وَإِن تَتَوَلَّوْاْ يَسْتَبْدِلْ قَوْماً غَيْرَكُمْ ثُمَّ لَا يَكُونُوا

And if you turn away, He will exchange you for some other people and they will not be your likes. (47:38)
