Surah An-Nisa — Ayah 45 (4:45)
وَٱللَّهُ أَعۡلَمُ بِأَعۡدَآئِكُمۡۚ وَكَفَىٰ بِٱللَّهِ وَلِيّٗا وَكَفَىٰ بِٱللَّهِ نَصِيرٗا ٤٥
English translation (Saheeh International)
And Allāh is most knowing of your enemies; and sufficient is Allāh as an ally, and sufficient is Allāh as a helper.
Brief commentary
Allah knows your enemies better than you do, O believers, so He informs you of them and makes clear to you that they are against you. Allah is enough as a Protector, keeping you safe from them harming you; and Allah is enough as a Helper, stopping them from plotting against you and from hurting you.
