Al-Ahzab 33:18

وَلَقَدْ كَانُوا عَاهَدُوا اللَّهَ مِن قَبْلُ لَا يُوَلُّونَ الْأَدْبَارَ ۚ وَكَانَ عَهْدُ اللَّهِ مَسْئُولًا

And they had already promised Allah before not to turn their backs and flee. And ever is the promise to Allah [that about which one will be] questioned.

قُل لَّن يَنفَعَكُمُ الْفِرَارُ إِن فَرَرْتُم مِّنَ الْمَوْتِ أَوِ الْقَتْلِ وَإِذًا لَّا تُمَتَّعُونَ إِلَّا قَلِيلًا

Say, [O Muhammad], "Never will fleeing benefit you if you should flee from death or killing; and then [if you did], you would not be given enjoyment [of life] except for a little."

قُلْ مَن ذَا الَّذِي يَعْصِمُكُم مِّنَ اللَّهِ إِنْ أَرَادَ بِكُمْ سُوءًا أَوْ أَرَادَ بِكُمْ رَحْمَةً ۚ وَلَا يَجِدُونَ لَهُم مِّن دُونِ اللَّهِ وَلِيًّا وَلَا نَصِيرًا

Say, "Who is it that can protect you from Allah if He intends for you an ill or intends for you a mercy?" And they will not find for themselves besides Allah any protector or any helper.

أَشِحَّةً عَلَيْكُمْ ۖ فَإِذَا جَاءَ الْخَوْفُ رَأَيْتَهُمْ يَنظُرُونَ إِلَيْكَ تَدُورُ أَعْيُنُهُمْ كَالَّذِي يُغْشَىٰ عَلَيْهِ مِنَ الْمَوْتِ ۖ فَإِذَا ذَهَبَ الْخَوْفُ سَلَقُوكُم بِأَلْسِنَةٍ حِدَادٍ أَشِحَّةً عَلَى الْخَيْرِ ۚ أُولَـٰئِكَ لَمْ يُؤْمِنُوا فَأَحْبَطَ اللَّهُ أَعْمَالَهُمْ ۚ وَكَانَ ذَٰلِكَ عَلَى اللَّهِ يَسِيرًا

Indisposed toward you. And when fear comes, you see them looking at you, their eyes revolving like one being overcome by death. But when fear departs, they lash you with sharp tongues, indisposed toward [any] good. Those have not believed, so Allah has rendered their deeds worthless, and ever is that, for Allah, easy.

يَحْسَبُونَ الْأَحْزَابَ لَمْ يَذْهَبُوا ۖ وَإِن يَأْتِ الْأَحْزَابُ يَوَدُّوا لَوْ أَنَّهُم بَادُونَ فِي الْأَعْرَابِ يَسْأَلُونَ عَنْ أَنبَائِكُمْ ۖ وَلَوْ كَانُوا فِيكُم مَّا قَاتَلُوا إِلَّا قَلِيلًا

They think the companies have not [yet] withdrawn. And if the companies should come [again], they would wish they were in the desert among the bedouins, inquiring [from afar] about your news. And if they should be among you, they would not fight except for a little.

لَّقَدْ كَانَ لَكُمْ فِي رَسُولِ اللَّهِ أُسْوَةٌ حَسَنَةٌ لِّمَن كَانَ يَرْجُو اللَّهَ وَالْيَوْمَ الْآخِرَ وَذَكَرَ اللَّهَ كَثِيرًا

There has certainly been for you in the Messenger of Allah an excellent pattern for anyone whose hope is in Allah and the Last Day and [who] remembers Allah often.
