Cowardice

Āl-‘Imrān 3:156

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ لَا تَكُونُواْ كَٱلَّذِينَ كَفَرُواْ وَقَالُواْ لِإِخۡوَٰنِهِمۡ إِذَا ضَرَبُواْ فِي ٱلۡأَرۡضِ أَوۡ كَانُواْ غُزّٗى لَّوۡ كَانُواْ عِندَنَا مَا مَاتُواْ وَمَا قُتِلُواْ لِيَجۡعَلَ ٱللَّهُ ذَٰلِكَ حَسۡرَةٗ فِي قُلُوبِهِمۡۗ وَٱللَّهُ يُحۡيِۦ وَيُمِيتُۗ وَٱللَّهُ بِمَا تَعۡمَلُونَ بَصِيرٞ ١٥٦

O you who have believed, do not be like those who disbelieved and said about their brothers when they traveled through the land or went out to fight, "If they had been with us, they would not have died or have been killed," so Allah makes that [misconception] a regret within their hearts. And it is Allah who gives life and causes death, and Allah is Seeing of what you do.

An-Nisā’ 4:72

وَإِنَّ مِنكُمۡ لَمَن لَّيُبَطِّئَنَّ فَإِنۡ أَصَٰبَتۡكُم مُّصِيبَةٞ قَالَ قَدۡ أَنۡعَمَ ٱللَّهُ عَلَيَّ إِذۡ لَمۡ أَكُن مَّعَهُمۡ شَهِيدٗا ٧٢

And indeed, there is among you he who lingers behind; and if disaster strikes you, he says, "Allah has favored me in that I was not present with them."

An-Nisā’ 4:73

وَلَئِنۡ أَصَٰبَكُمۡ فَضۡلٞ مِّنَ ٱللَّهِ لَيَقُولَنَّ كَأَن لَّمۡ تَكُنۢ بَيۡنَكُمۡ وَبَيۡنَهُۥ مَوَدَّةٞ يَٰلَيۡتَنِي كُنتُ مَعَهُمۡ فَأَفُوزَ فَوۡزًا عَظِيمٗا ٧٣

But if bounty comes to you from Allah, he will surely say, as if there had never been between you and him any affection. "Oh, I wish I had been with them so I could have attained a great attainment."

Al-Anfāl 8:15

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓاْ إِذَا لَقِيتُمُ ٱلَّذِينَ كَفَرُواْ زَحۡفٗا فَلَا تُوَلُّوهُمُ ٱلۡأَدۡبَارَ ١٥

O you who have believed, when you meet those who disbelieve advancing [for battle], do not turn to them your backs [in flight].

Al-Anfāl 8:16

وَمَن يُوَلِّهِمۡ يَوۡمَئِذٖ دُبُرَهُۥٓ إِلَّا مُتَحَرِّفٗا لِّقِتَالٍ أَوۡ مُتَحَيِّزًا إِلَىٰ فِئَةٖ فَقَدۡ بَآءَ بِغَضَبٖ مِّنَ ٱللَّهِ وَمَأۡوَىٰهُ جَهَنَّمُۖ وَبِئۡسَ ٱلۡمَصِيرُ ١٦

And whoever turns his back to them on such a day, unless swerving [as a strategy] for war or joining [another] company, has certainly returned with anger [upon him] from Allah, and his refuge is Hell - and wretched is the destination.

At-Taubah 9:44

لَا يَسۡتَـٔۡذِنُكَ ٱلَّذِينَ يُؤۡمِنُونَ بِٱللَّهِ وَٱلۡيَوۡمِ ٱلۡأٓخِرِ أَن يُجَٰهِدُواْ بِأَمۡوَٰلِهِمۡ وَأَنفُسِهِمۡۗ وَٱللَّهُ عَلِيمُۢ بِٱلۡمُتَّقِينَ ٤٤

Those who believe in Allah and the Last Day would not ask permission of you to be excused from striving with their wealth and their lives. And Allah is Knowing of those who fear Him.

At-Taubah 9:49

وَمِنۡهُم مَّن يَقُولُ ٱئۡذَن لِّي وَلَا تَفۡتِنِّيٓۚ أَلَا فِي ٱلۡفِتۡنَةِ سَقَطُواْۗ وَإِنَّ جَهَنَّمَ لَمُحِيطَةُۢ بِٱلۡكَٰفِرِينَ ٤٩

And among them is he who says, "Permit me [to remain at home] and do not put me to trial." Unquestionably, into trial they have fallen. And indeed, Hell will encompass the disbelievers.

At-Taubah 9:56

وَيَحۡلِفُونَ بِٱللَّهِ إِنَّهُمۡ لَمِنكُمۡ وَمَا هُم مِّنكُمۡ وَلَٰكِنَّهُمۡ قَوۡمٞ يَفۡرَقُونَ ٥٦

And they swear by Allah that they are from among you while they are not from among you; but they are a people who are afraid.

At-Taubah 9:57

لَوۡ يَجِدُونَ مَلۡجَـًٔا أَوۡ مَغَٰرَٰتٍ أَوۡ مُدَّخَلٗا لَّوَلَّوۡاْ إِلَيۡهِ وَهُمۡ يَجۡمَحُونَ ٥٧

If they could find a refuge or some caves or any place to enter [and hide], they would turn to it while they run heedlessly.
