This sect is considered to be the followers of Najda ibn Amir Hanafi (d. 69 AH). Initially, Najda ibn Amir with his army in Yamamah intended to join the Khawarij army of Basra led by Nafi ibn Azraq. In the meantime, Nafi expressed his own views and considered the Khawarij followers as infidels and polytheists like other Muslims and considered it permissible to kill them and their women and children. After the incident, a group of Nafi's companions separated from him and headed towards Yamamah. Ibn Amir rushed to welcome them and learned of Nafi's new views and opposed him. Then, a splinter group from Azraqa pledged allegiance to Najda ibn Amir along with the Khawarij of Yamamah, and thus the Najdat were born. This group is also known as the A'zari, because their belief is that they consider ignorance of the branches of religion to be an excuse. Overall, this group has moderate beliefs and has distanced itself from the extremism of the Khawarij to some extent. The views of this sect:

1 - If someone commits a minor sin and insists on it and repeats it, he is a polytheist, but if someone commits major sins such as adultery, theft, and drinking alcohol and does not insist on it, he is a Muslim. Therefore, only sins that a person insists on are grounds for disbelief and gratitude.

2 - The people and society do not need a leader and an Imam, and they only need to observe justice, and if this work stops without the presence of an Imam, then the appointment of an Imam is necessary.

3 - Taqiyyah in speech and action is permissible.

4 - Killing the children of opponents is not permissible.

5 - The Khawarij are excused.

The Najdat soon suffered from internal divisions, and the leader of one of these splinter groups, Najdat ibn Amir, was killed.
