Surah At-Taubah (The Repentance), Verse 29

قَاتِلُوا الَّذِیْنَ لَا یُؤْمِنُوْنَ بِاللّٰهِ وَلَا بِالْیَوْمِ الْاٰخِرِ وَلَا یُحَرِّمُوْنَ مَا حَرَّمَ اللّٰهُ وَرَسُوْلُهٗ وَلَا یَدِیْنُوْنَ دِیْنَ الْحَقِّ مِنَ الَّذِیْنَ اُوْتُوا الْكِتٰبَ حَتّٰی یُعْطُوا الْجِزْیَةَ عَنْ یَّدٍ وَّهُمْ صٰغِرُوْنَ 

Qaatilul lazeena laa yu'minoona billaahi wa laa bil yawmil Aakhiri wa laa yuharrimoona maa harramal laahu wa Rasooluhoo wa laa yadeenoona deenal haqqi minal lazeena ootul Kitaaba hattaa yu'tul jizyata ai yadinw wa hum saaghiroon

“Fight those who believe not in Allah nor the Last Day, nor hold that forbidden which hath been forbidden by Allah and His Messenger, nor acknowledge the religion of Truth, (even if they are) of the People of the Book, until they pay the Jizya with willing submission, and feel themselves subdued.”

Quran 9:29 (Yusuf Ali Translation)
