وَمِنَ النَّاسِ مَن يَقُولُ آمَنَّا بِاللّهِ وَبِالْيَوْمِ الآخِرِ وَمَا هُم بِمُؤْمِنِينَ
[2:8]
And there are some people who say: We believe in Allah and the last day; and they are not at all believers.
Of the people there are some who say: "We believe in Allah and the Last Day;" but they do not (really) believe.
And of mankind are some who say: We believe in Allah and the Last Day, when they believe not.
