La yuqatiloonakum jameeAAan illa fee quran muhassanatin aw min wara-i judurin ba'suhum (surah Al Hashr: 14)

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(59:14) They will never fight against you as a body (in an open battlefield); and if they fight against you they will fight only in fortified townships or from behind walls. Intense is their hostility to one another. You reckon them united while their hearts are divided. *25 That is because they are a people devoid of reason.

Laa yuqaatiloonakum jamee`an illaa fee quram muhas sanatin aw minw waraaa`i judur; baasuhum bainahum shadeed; tahsabuhum jamee`anw-wa quloobuhum shatta; zaalika biannahum qawmul laa ya`qiloon

*25) This refers to the second weakness of the hypocrites. The first weakness was that they were cowardly: they feared the men instead of fearing God and had no higher aim of lift before them like the believers, which might impel them to fight for it even at the cost of life. And their second weakness was that they had no common tic between them except hypocrisy, which might unite them together into a strong band. The only thing that had brought them together was that they were all feeling highly upset at the flourishing leadership and rulership of Muhammad (upon whom be Allah's peace and blessings). who was an outsider in their city, and at the warm reception and help which their own compartriots the Ansar were giving the Emigrants. Because of this jealousy they wanted them to join hands together and in conspiracy with the enemies of Islam of the surrounding areas should somehow put an end to this alien power and authority. But apart from this negative objective there was no positive common aim to unify them. Each of their chiefs had his own separate band: each craved for his own leadership; no one was sincere to the other; but each bore such jealousy and malice for the other that they could neither forget their mutual enmities nor desist from harming the other fatally even while facing those whom they regarded as their common enemy. Thus, at the outset, even before the battle against the Bani an-Nadir took place, Allah analysed the internal state of the hypocrites and informed the Muslims that there was no real danger from their side; therefore, they should not feel alarmed- at the rumours that when they lay siege to the Bani an-Nadir, the leaders of the hypocrites would attack them from the rear with two thousand men, and also bring the Bani Quraizah and the Bani Ghatafan along against them. AII this was empty boasting which would be exposed at the very beginning of the trial.
