Belief in Parts

Those who reject Allah and His messengers, seeking to divide faith, believing in some while denying others, are truly misguided.

4:150Lo! those who disbelieve in Allah and His messengers, and seek to make distinction between Allah and His messengers, and say: We believe in some and disbelieve in others, and seek to choose a way in between;

These are truly the disbelievers.

4:151Such are disbelievers in truth; and for disbelievers We prepare a shameful doom.

Among them are those who believe, and others who do not.

10:40And of them is he who believeth therein, and of them is he who believeth not therein, and thy Lord is Best Aware of the corrupters.
