When the Naṣārā would not accept the teachings of Muḥammad, the Qurʾān began to declare the independence of the Muslims.
With the fairly sizeable community of Christians in Najrān, a treaty was made, in which Muḥammad allowed them freedom to practise their religion and to keep their property; treaties were similarly made with Christian tribes in the Arabian peninsula. Later, however, ʿUmar had the majority of the Najrān Christians exiled to Iraq.
