How was it 'out of context' according to you then?Not really as he took the verse out of its context in order to do it. Also he wasn't a Jew and had no authority to sit in judgement over the Qurayza nor to interpret their scripture for them.
@Tumah @Flankerl @RabbiO, what do you make of this notion that Muhammad used a passage from Deuteronomy to judge the Banu Qurayza according to 'Jewish law'? Do you think the Qurayza would have been okay with a non-Jew doing this?
The Banu Qurayza chose Sa'd ibn Mu'adh to judge and said they would agree with his decision.
