Al-Anfal 8:55

<h2>Striking Hard against Those Who disbelieve and break the Covenants</h2><p>Allah states here that the worst moving creatures on the face of the earth are those who disbelieve, who do not embrace the faith, and break promises whenever they make a covenant, even when they vow to keep them, </p><div class="arabic uthmani">وَهُمْ لاَ يَتَّقُونَ</div><p>(and they do not have Taqwa) meaning they do not fear Allah regarding any of the sins they commit. </p><div class="arabic uthmani">فَإِمَّا تَثْقَفَنَّهُمْ فِى الْحَرْبِ</div><p>(So if you gain the mastery over them in war), if you defeat them and have victory over them in war, </p><div class="arabic uthmani">فَشَرِّدْ بِهِم مَّنْ خَلْفَهُمْ</div><p>(then disperse those who are behind them,) by severely punishing the captured people according to Ibn `Abbas, Al-Hasan Al-Basri, Ad-Dahhak, As-Suddi, `Ata' Al-Khurasani and Ibn `Uyaynah. This Ayah commands punishing them harshly and inflicting casualties on them. This way, other enemies, Arabs and non-Arabs, will be afraid and take a lesson from their end, </p><div class="arabic uthmani">لَعَلَّهُمْ يَذَّكَّرُونَ</div><p>(so that they may learn a lesson. ) </p><p>As-Suddi commented, "They might be careful not to break treaties, so that they do not meet the same end." </p>

Lo! the worst of beasts in Allah's sight are the ungrateful who will not believe.

For the worst of beasts in the sight of Allah are those who reject Him: They will not believe.

Verily, The worst of moving (living) creatures before Allah are those who disbelieve, - so they shall not believe.

The worst of creatures in God's view are those who disbelieve. They have no faith.
