﴿ يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ قَٰتِلُوا۟ ٱلَّذِينَ يَلُونَكُم مِّنَ ٱلْكُفَّارِ وَلْيَجِدُوا۟ فِيكُمْ غِلْظَةًۭ ۚ وَٱعْلَمُوٓا۟ أَنَّ ٱللَّهَ مَعَ ٱلْمُتَّقِينَ ﴾

“O you who have attained to faith! Fight against those deniers of the truth who are near you, and let them find you adamant; and know that. God is with those who are conscious of Him.”

O you who believe, fight those [of the disbelievers] who are near to you, from among the disbelieving faculties of your souls, which are the most hostile of your enemies, and let them find harshness in you, that is, a vanquishing and a severity until you attaint the degree of God-fearing so that there then descends upon you assistance from God as He says: and know that God is with the God-fearing.
