The psychology of disbelief

وَإِذَا ذُكِرَ ٱللَّهُ وَحْدَهُ ٱشْمَأَزَّتْ قُلُوبُ ٱلَّذِينَ لَا يُؤْمِنُونَ بِٱلْـَٔاخِرَةِ ۖ وَإِذَا ذُكِرَ ٱلَّذِينَ مِن دُونِهِۦٓ إِذَا هُمْ يَسْتَبْشِرُونَ

And when Allāh is mentioned alone, the hearts of those who do not believe in the Hereafter shrink with aversion, but when those [worshipped] other than Him are mentioned, immediately they rejoice.
