The Holy Quran 9:13 — Surah At-Tawbah
Arabic text
أَلَا تُقَـٰتِلُونَ قَوْمًا نَّكَثُوٓا۟ أَيْمَـٰنَهُمْ وَهَمُّوا۟ بِإِخْرَاجِ ٱلرَّسُولِ وَهُم بَدَءُوكُمْ أَوَّلَ مَرَّةٍ ۚ أَتَخْشَوْنَهُمْ ۚ فَٱللَّهُ أَحَقُّ أَن تَخْشَوْهُ إِن كُنتُم مُّؤْمِنِينَ
Translation
Will you not fight a nation (the Mushrikeen of Makkah) that breaks its promises (oaths and treaties), resolves to drive out the Rasool (from his hometown of Makkah) and started (the fight) against you the first time around (by attacking your allies, thereby breaking the Treaty of Hudaybiyyah). Do you fear them? Allaah is more worthy of being feared, (and You will rather fear Him) if you are Mu'mineen. (True Mu'mineen know that no one can harm them without Allaah's will.)
Tafsir (excerpt) — Tafsir Usmani
the Quraysh had broken their oaths and treaties, for, in violation of the treaty, they helped the Banu Bakr against the Khuza'ah, and before the Hijrah they devised plans to expel the Prophet ﷺ from his sacred homeland (Makkah the Venerated).
