﴿ هُوَ ٱلَّذِى جَعَلَكُمْ خَلَٰٓئِفَ فِى ٱلْأَرْضِ ۚ فَمَن كَفَرَ فَعَلَيْهِ كُفْرُهُۥ ۖ وَلَا يَزِيدُ ٱلْكَٰفِرِينَ كُفْرُهُمْ عِندَ رَبِّهِمْ إِلَّا مَقْتًۭا ۖ وَلَا يَزِيدُ ٱلْكَٰفِرِينَ كُفْرُهُمْ إِلَّا خَسَارًۭا ﴾

“He it is who has made you inherit the earth. Hence, he who is bent on denying the truth [of God’s oneness and uniqueness ought to know that] this denial of his will fall back upon him: for their [per­sistent] denial of this truth does but add to the deniers’ loathsomeness in their Sustainer’s sight and, thus, their denial of this truth does but add to the deniers’ loss.”

It is He Who made you successors in the earth khalā’if ‘successors’ is the plural of khalīfa in other words one succeeding the other. So whoever disbelieves of you his disbelief will be to his own detriment that is the evil consequences of his disbelief will be so. And their disbelief does not increase the disbelievers with their Lord in anything except disfavour wrath. And their disbelief does not increase the disbelievers in anything except loss of the reward of the Hereafter.
