The verse instructing qitāl against People of the Book until they pay the jizyah.
These verses are grouped by theme as a starting point — not as standalone rulings. A verse takes on its full meaning only in context: the verses before and after, the occasion of revelation (asbāb al-nuzūl) and the explanation of the scholars. So read each verse in full via the tafsir, and consult a qualified scholar when in doubt.
قَٰتِلُوا۟ ٱلَّذِينَ لَا يُؤْمِنُونَ بِٱللَّهِ وَلَا بِٱلْيَوْمِ ٱلْءَاخِرِ وَلَا يُحَرِّمُونَ مَا حَرَّمَ ٱللَّهُ وَرَسُولُهُۥ وَلَا يَدِينُونَ دِينَ ٱلْحَقِّ مِنَ ٱلَّذِينَ أُوتُوا۟ ٱلْكِتَٰبَ حَتَّىٰ يُعْطُوا۟ ٱلْجِزْيَةَ عَن يَدٍۢ وَهُمْ صَٰغِرُونَ
Fight those of Ahl al-Kitāb who do not believe in Allah or the Last Day — until they pay the jizyah by hand, in submission.
