Shaikh Bin Baz rahimahullah took that opinion. He said rahimahullah:
“…And the seventy sects who are promised the Hell-fire, among them are disbelievers and innovators. Whoever among them dies upon disbelief, then for him is the Hell-fire forever abiding therein and whoever dies upon innovation which is less than disbelief or disobedience which is less than disbelief, then he is under the will of Allah. He is promised the Hell-fire. So like this, it is known that they are not all disbelievers. Rather some of them are disbelievers and some of them are disobedient and innovators
Likewise the Scholars I mentioned in the brief article here mentioned groups like the Raafidah.
Other Scholars, on the other hand, do not include groups like the Jahmiyyah as part of the seventy two sects. This is because the Jahmiyyah were declared as disbelievers.
Shaikh Abdul Muhsin al-‘Abbad (may Allah preserve him) said:
May Allah preserve you, do the Scholars determine or enumerate the sects which come in the Hadith about seventy three sects? And are the Jahmiyyah part of the seventy three sects?
“The Scholars mention the origin of these sects. As for the Jahmiyyah, then some of the People of Knowledge did not count them as not being part of the seventy two sects. This is because the seventy two sects are from the Ummatul-Ijaabah (the nation who answered the call). They are from the Muslims. So like this, some of the Scholars or a group from the Scholars have declared the Jahmiyyah as disbelievers. They said they are outside the seventy two sects and not part of the seventy two sects which are Islamic sects”
