ذَلِكُمْ وَأَنَّ اللّهَ مُوهِنُ كَيْدِ الْكَافِرِينَ
[8:18]
This, and that Allah is the weakener of the struggle of the unbelievers.
That, and also because Allah is He Who makes feeble the plans and stratagem of the Unbelievers.
That (is the case); and (know) that Allah (it is) Who maketh weak the plan of disbelievers.
