Quran 9:96 — Ultimatum (Bara'ah)

يَحلِفونَ لَكُم لِتَرضَوا عَنهُم ۖ فَإِن تَرضَوا عَنهُم فَإِنَّ اللَّهَ لا يَرضىٰ عَنِ القَومِ الفٰسِقينَ

They swear to you, that you may pardon them. Even if you pardon them, GOD does not pardon such wicked people.

[9:95] They will swear by GOD to you, when you return to them, that you may disregard them. Do disregard them. They are polluted, and their destiny is Hell, as a requital for the sins they have earned.

[9:97] The Arabs are the worst in disbelief and hypocrisy, and the most likely to ignore the laws that GOD has revealed to His messenger. GOD is Omniscient, Most Wise.
