﴿ 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 ye who believe!) in Muhammad (pbuh) and in the Qur'an (Fight those of the disbelievers who are near to you) the Banu Qurayzah, Banu'l-Nadir, Fadak and Khaybar, (and let them find harshness in you) toughness from you, (and know) O believers (that Allah is with those who keep their duty (unto Him)) Allah helps the believers: Muhammad (pbuh) and his Companions, by making them victorious over their enemies.
