Surah Al-Ahzab — Ayah 14 (33:14)
وَلَوۡ دُخِلَتۡ عَلَيۡهِم مِّنۡ أَقۡطَارِهَا ثُمَّ سُئِلُواْ ٱلۡفِتۡنَةَ لَأٓتَوۡهَا وَمَا تَلَبَّثُواْ بِهَآ إِلَّا يَسِيرٗا ١٤
English translation (Saheeh International)
And if they had been entered upon from all its [surrounding] regions and fitnah [i.e., disbelief] had been demanded of them, they would have done it and not hesitated over it except briefly.
Brief commentary
And if the enemy were to enter upon them in Madina from all its sides and ask them to return to disbelieving and associating partners with Allah, they would grant their enemy this, and they would not lag behind from becoming renegade and turning back towards disbelief except a little.
