The theme of ‘help’ is ubiquitous in the Qurān. In it, composites of the root n-ṣ-r appear approximately 120 times with that meaning. But more explicitly, in the sūras that are traditionally associated with the Medinan period (particularly, sūras 5, 8 and 9), this theme comes to light as the idea of a concrete aid given by God to those who fight for Him: this idea appears twelve times, and in two of these, there is a passage of several verses where the verb naṣara or the substantive naṣr is explicitly stated ten times.

This help from God can take on several aspects. The Qurān sometimes insists on the contrast between the divine plan and the limited vision of humans: it is then a question of divine inspiration as to the decision to fight, in spite of the reluctance of some people (Q 3:5; 33:11–15), or not to give in to the temptation to flee (Q 9:25). Sometimes it might be a designation of a more significant goal than that envisioned by human calculations (Q 8:7). Sometimes, it is purely and simply the affirmation of the fact that it is only in God that efficiency resides: God ‘turns away the hands’ of adversaries (Q 5:11), it is He Himself, and not the believers, who kills the infidels (Q 8:17); He sends ‘invisible’ cohorts (Q 33:9; 9:26) – i.e. angels – the thousands of which can multiply (Q 8:9; 3:124–5).

This twofold perspective finds extended discussion in the description of the aim of this help. The Qurān insists on the concrete aspect – that is, ‘the torment of infidels’ (Q 9:26), the effective victory (Q 3:127) that can be granted only by that divine help (Q 3:160); the announcement of that happy event is a piece of good news which ‘tranquillises the hearts (of believers)’ (Q 8:10; 3:126) and ‘heals’ them (Q 9:14). It ‘makes believers feel God's favour’ (Q 8:17) or, even more, it ‘makes the sakīna [that is, the divine presence] descend into the hearts of believers’ (Q 48:4); and this sakīna is explicitly linked with military success (fa-anzala al-sakīna alayhim wa-athābahum fatḥan qarīban, Q 48:18; cf. also 9:26).
