﴿ وَمِنَ ٱلنَّاسِ مَن يَقُولُ ءَامَنَّا بِٱللَّهِ فَإِذَآ أُوذِىَ فِى ٱللَّهِ جَعَلَ فِتْنَةَ ٱلنَّاسِ كَعَذَابِ ٱللَّهِ وَلَئِن جَآءَ نَصْرٌۭ مِّن رَّبِّكَ لَيَقُولُنَّ إِنَّا كُنَّا مَعَكُمْ ۚ أَوَلَيْسَ ٱللَّهُ بِأَعْلَمَ بِمَا فِى صُدُورِ ٱلْعَٰلَمِينَ ﴾

“Now there is among men many a one who says [of himself and of others like him], “We do believe in God” - but whenever he is made to suffer in God’s cause, he thinks that persecution at the hands of man is as [much to be feared, or even more than,] God’s chastisement; whereas, if succour from thy Sustainer comes [to those who truly believe] he is sure to say. “Behold, we have always been with you!” Is not God fully aware of what is in the hearts of all creatures?”

When one who calls himself a believer, or mu’min, shows himself to be such only when some advantage is to be gained, but otherwise recants, he reveals himself to be what the Quran calls a hypocrite, or munafiq. A believer in name only, he is not prepared to pay the price of his faith. He and other people like him fail at the very juncture where they are most required to prove their moral worth.
