Allah's Signs displayed during Badr, And throwing Sand in the Eyes of the Disbelievers

Allah states that He creates the actions that the servants perform and that whatever good actions they take, it is He Who should be praised for them, for He directed and helped them perform these actions. Allah said,

فَلَمْ تَقْتُلُوهُمْ وَلَـكِنَّ اللَّهَ قَتَلَهُمْ

In contrast to this, yet another benefit which came out of this victory has been described in the fourth verse as: ذَٰلِكُمْ وَأَنَّ اللَّـهَ مُوهِنُ كَيْدِ الْكَافِرِ‌ينَ ﴿18﴾ (Apart from that, Allah is the One who frustrates the device of the disbelievers - 18). In other words, it can be said that Muslims were blessed with this victory for yet another reason, that is, the plans of the disbelievers should be rendered ineffective through it, something which would make them understand that Divine support is not with them - and no plan can succeed without it.

The fifth verse (19) carries an address to the defeated disbelievers from the tribe of Quraysh and refers to an event which came to pass when the Quraysh army was about to depart Makkah on their mission to confront Muslims.
