Assalamu Alaikum Brothers in Islam,
I was reading the conquest of Khaibar and although Alhamdulillah I don't doubt the decision taken by our Holy Prophet Muhammed (saw) , I do feel a bit uncomfortable at the fact that the conquest was mostly a pre emptive strike.
The People (Jews) of Khaibar surely were treacherous and a threat but we're not openly engaged in a war with the Muslim.
Are the reports of Ibn Ishaq or other writers trustworthy regarding this?
Were conquests like these considered the "norm" back then?
