Sura al-Tawbah 9:123

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ قَٰتِلُوا۟ ٱلَّذِينَ يَلُونَكُم مِّنَ ٱلْكُفَّارِ وَلْيَجِدُوا۟ فِيكُمْ غِلْظَةً وَٱعْلَمُوٓا۟ أَنَّ ٱللَّـهَ مَعَ ٱلْمُتَّقِينَ

yā-ayyuhā lladhīna āmanū qātilū lladhīna yalūnakum mina l-kuffāri wa-l-yajidu fīkum ghilẓatan wa-iʿlamū annā allāha maʿa l-muttaqīna

O ye who believe! fight the unbelievers who gird you about, and let them find firmness in you: and know that Allah is with those who fear Him.
