The Quran

هُوَ الَّذي أَخرَجَ الَّذينَ كَفَروا مِن أَهلِ الكِتابِ مِن دِيارِهِم لِأَوَّلِ الحَشرِ ۚ ما ظَنَنتُم أَن يَخرُجوا ۖ وَظَنّوا أَنَّهُم مانِعَتُهُم حُصونُهُم مِنَ اللَّهِ فَأَتاهُمُ اللَّهُ مِن حَيثُ لَم يَحتَسِبوا ۖ وَقَذَفَ في قُلوبِهِمُ الرُّعبَ ۚ يُخرِبونَ بُيوتَهُم بِأَيديهِم وَأَيدِي المُؤمِنينَ فَاعتَبِروا يا أُولِي الأَبصارِ

Muhammad Asad

He it is who turned out of their homes, at the time of [their] first gathering [for war], such of the followers of earlier revelation as were bent on denying the truth.¹ You did not think [O believersj that they would depart [without resistance] - just as they thought that their strongholds would protect them against God: but God came upon them in a manner which they had not expected,² and cast terror into their hearts; [and thus] they destroyed their homes by their own hands as well as the hands of the believers.³ Learn a lesson, then, O you who are endowed with insight!

For this and the subsequent historical references, see the introductory note to this surah. The tribe of Banu 'n-Nadir - who, as Jews, are naturally termed ahl al-kitab ("followers of earlier revelation") - are characterized as "such as were bent on denying the truth" (alladhina kafaru, see note 6 on 2:6) because they treacherously turned against the Prophet despite their earlier admission that he was truly the bearer of God's message announced in their own holy scriptures (Deuteronomy xviii, 15 and 18).
Lit., "from whence they bad not thought [it possible]": an allusion to the last-minute, unexpected failure of 'Abd Allah ibn Ubayy to come to their aid.
As mentioned in the introductory note, the Banu 'n-Nadir had originally concluded a treaty of mutual non-interference with the Muslim community, and were to live at Medina as its friendly neighbours; and even later, when their hostility to the Muslims had become apparent and they were ordered to emigrate, they were to be allowed to retain ownership of their plantations. Subsequently, however, they forfeited by their treachery both their citizenship and the rights to their landed property, and thus "destroyed their homes by their own hands".
