يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ قَٰتِلُواْ ٱلَّذِينَ يَلُونَكُم مِّنَ ٱلۡكُفَّارِ وَلۡيَجِدُواْ فِيكُمۡ غِلۡظَةٗۚ وَٱعۡلَمُوٓاْ أَنَّ ٱللَّهَ مَعَ ٱلۡمُتَّقِينَ ١٢٣
O you who have believed, fight against those adjacent to you of the disbelievers and let them find in you harshness. And know that Allāh is with the righteous.
Translation: Saheeh International (English)
Each word's meaning and sound
O you who believe, fight against those who oppose the truth who are near to you, because of the danger they pose to you because of their proximity; and show strength in order to inspire fear in them and drive away their evil. Allah is with the Allah-conscious believers with His help and support.
