The Holy Quran 9:47 — Surah At-Tawbah
Arabic text
لَوْ خَرَجُوا۟ فِيكُم مَّا زَادُوكُمْ إِلَّا خَبَالًا وَلَأَوْضَعُوا۟ خِلَـٰلَكُمْ يَبْغُونَكُمُ ٱلْفِتْنَةَ وَفِيكُمْ سَمَّـٰعُونَ لَهُمْ ۗ وَٱللَّهُ عَلِيمٌۢ بِٱلظَّـٰلِمِينَ
Translation
(Allaah had destined that these people should not join the Muslim army because) Had they proceeded with you, they would have added nothing but conflict (to the Muslim ranks) and would have hurried to and fro among you, seeking to cause trouble (by carrying tales and spreading false information). (However, you should still be careful because) Among you are those who spy for them. Allaah is well aware of the oppressors (those who try to cause trouble among people).
Tafsir (excerpt) — Tafsir Usmani
that is, had they set out with you, they would through their cowardice and faintheartedness have weakened the resolve of others too, would have tried to sow division among the Muslims by setting them against one another, and by spreading false rumours would have sought to make them fear the enemy.
