When the Quran describes believers as fighting “in the way of Allah,” it makes a theological claim by associating Allah with human fighting. See the analysis of these expressions at 73.20.

This is the only verse in the Quran that brings the Torah ( tawrāt ), Gospel ( injīl ), and qur ’ ān (lit. “recitation”) together. The Quran claims here that the particular point on which the Torah and Gospel agree with the Muslim recitation is that believers “fight in the way of Allah, and they kill and are killed.”

This verse makes the reader question whether the Quran has a clear idea of the contents of the Torah and Gospel. A similar question is raised by 61.14, which appears to say that ‘Īsā and his disciples fought against their enemies (cf. 3.52). Along with these misunderstandings, the Quran gives no information about the peaceable teaching and example of Jesus in the Gospel accounts. See the analysis of the Quran’s verses on the “Gospel” at 57.27.

Do the Torah and Gospel in fact contain such a promise? See the comment on this characterization of the Bible at 61.14.
