in Allah's cause

Āl-‘Imrān 3:195

فَٱسۡتَجَابَ لَهُمۡ رَبُّهُمۡ أَنِّي لَآ أُضِيعُ عَمَلَ عَٰمِلٖ مِّنكُم مِّن ذَكَرٍ أَوۡ أُنثَىٰۖ بَعۡضُكُم مِّنۢ بَعۡضٖۖ فَٱلَّذِينَ هَاجَرُواْ وَأُخۡرِجُواْ مِن دِيَٰرِهِمۡ وَأُوذُواْ فِي سَبِيلِي وَقَٰتَلُواْ وَقُتِلُواْ لَأُكَفِّرَنَّ عَنۡهُمۡ سَيِّـَٔاتِهِمۡ وَلَأُدۡخِلَنَّهُمۡ جَنَّٰتٖ تَجۡرِي مِن تَحۡتِهَا ٱلۡأَنۡهَٰرُ ثَوَابٗا مِّنۡ عِندِ ٱللَّهِۚ وَٱللَّهُ عِندَهُۥ حُسۡنُ ٱلثَّوَابِ ١٩٥

And their Lord responded to them, "Never will I allow to be lost the work of [any] worker among you, whether male or female; you are of one another. So those who emigrated or were evicted from their homes or were harmed in My cause or fought or were killed - I will surely remove from them their misdeeds, and I will surely admit them to gardens beneath which rivers flow as reward from Allah, and Allah has with Him the best reward."

Al-Ḥajj 22:58

وَٱلَّذِينَ هَاجَرُواْ فِي سَبِيلِ ٱللَّهِ ثُمَّ قُتِلُوٓاْ أَوۡ مَاتُواْ لَيَرۡزُقَنَّهُمُ ٱللَّهُ رِزۡقًا حَسَنٗاۚ وَإِنَّ ٱللَّهَ لَهُوَ خَيۡرُ ٱلرَّٰزِقِينَ ٥٨

And those who emigrated for the cause of Allah and then were killed or died - Allah will surely provide for them a good provision. And indeed, it is Allah who is the best of providers.

Muḥammad 47:4

فَإِذَا لَقِيتُمُ ٱلَّذِينَ كَفَرُواْ فَضَرۡبَ ٱلرِّقَابِ حَتَّىٰٓ إِذَآ أَثۡخَنتُمُوهُمۡ فَشُدُّواْ ٱلۡوَثَاقَ فَإِمَّا مَنَّۢا بَعۡدُ وَإِمَّا فِدَآءً حَتَّىٰ تَضَعَ ٱلۡحَرۡبُ أَوۡزَارَهَاۚ ذَٰلِكَۖ وَلَوۡ يَشَآءُ ٱللَّهُ لَٱنتَصَرَ مِنۡهُمۡ وَلَٰكِن لِّيَبۡلُوَاْ بَعۡضَكُم بِبَعۡضٖۗ وَٱلَّذِينَ قُتِلُواْ فِي سَبِيلِ ٱللَّهِ فَلَن يُضِلَّ أَعۡمَٰلَهُمۡ ٤

So when you meet those who disbelieve [in battle], strike [their] necks until, when you have inflicted slaughter upon them, then secure their bonds, and either [confer] favor afterwards or ransom [them] until the war lays down its burdens. That [is the command]. And if Allah had willed, He could have taken vengeance upon them [Himself], but [He ordered armed struggle] to test some of you by means of others. And those who are killed in the cause of Allah - never will He waste their deeds.

An-Nisā’ 4:74

۞ فَلۡيُقَٰتِلۡ فِي سَبِيلِ ٱللَّهِ ٱلَّذِينَ يَشۡرُونَ ٱلۡحَيَوٰةَ ٱلدُّنۡيَا بِٱلۡأٓخِرَةِۚ وَمَن يُقَٰتِلۡ فِي سَبِيلِ ٱللَّهِ فَيُقۡتَلۡ أَوۡ يَغۡلِبۡ فَسَوۡفَ نُؤۡتِيهِ أَجۡرًا عَظِيمٗا ٧٤

So let those fight in the cause of Allah who sell the life of this world for the Hereafter. And he who fights in the cause of Allah and is killed or achieves victory - We will bestow upon him a great reward.

An-Nisā’ 4:77

أَلَمۡ تَرَ إِلَى ٱلَّذِينَ قِيلَ لَهُمۡ كُفُّوٓاْ أَيۡدِيَكُمۡ وَأَقِيمُواْ ٱلصَّلَوٰةَ وَءَاتُواْ ٱلزَّكَوٰةَ فَلَمَّا كُتِبَ عَلَيۡهِمُ ٱلۡقِتَالُ إِذَا فَرِيقٞ مِّنۡهُمۡ يَخۡشَوۡنَ ٱلنَّاسَ كَخَشۡيَةِ ٱللَّهِ أَوۡ أَشَدَّ خَشۡيَةٗۚ وَقَالُواْ رَبَّنَا لِمَ كَتَبۡتَ عَلَيۡنَا ٱلۡقِتَالَ لَوۡلَآ أَخَّرۡتَنَآ إِلَىٰٓ أَجَلٖ قَرِيبٖۗ قُلۡ مَتَٰعُ ٱلدُّنۡيَا قَلِيلٞ وَٱلۡأٓخِرَةُ خَيۡرٞ لِّمَنِ ٱتَّقَىٰ وَلَا تُظۡلَمُونَ فَتِيلًا ٧٧

Have you not seen those who were told, "Restrain your hands [from fighting] and establish prayer and give zakah"? But then when fighting was ordained for them, at once a party of them feared men as they fear Allah or with [even] greater fear. They said, "Our Lord, why have You decreed upon us fighting? If only You had postponed [it for] us for a short time." Say, The enjoyment of this world is little, and the Hereafter is better for he who fears Allah. And injustice will not be done to you, [even] as much as a thread [inside a date seed]."

An-Nisā’ 4:84

فَقَٰتِلۡ فِي سَبِيلِ ٱللَّهِ لَا تُكَلَّفُ إِلَّا نَفۡسَكَۚ وَحَرِّضِ ٱلۡمُؤۡمِنِينَۖ عَسَى ٱللَّهُ أَن يَكُفَّ بَأۡسَ ٱلَّذِينَ كَفَرُواْۚ وَٱللَّهُ أَشَدُّ بَأۡسٗا وَأَشَدُّ تَنكِيلٗا ٨٤

So fight, [O Muhammad], in the cause of Allah; you are not held responsible except for yourself. And encourage the believers [to join you] that perhaps Allah will restrain the [military] might of those who disbelieve. And Allah is greater in might and stronger in [exemplary] punishment.

At-Taubah 9:38

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ مَا لَكُمۡ إِذَا قِيلَ لَكُمُ ٱنفِرُواْ فِي سَبِيلِ ٱللَّهِ ٱثَّاقَلۡتُمۡ إِلَى ٱلۡأَرۡضِۚ أَرَضِيتُم بِٱلۡحَيَوٰةِ ٱلدُّنۡيَا مِنَ ٱلۡأٓخِرَةِۚ فَمَا مَتَٰعُ ٱلۡحَيَوٰةِ ٱلدُّنۡيَا فِي ٱلۡأٓخِرَةِ إِلَّا قَلِيلٌ ٣٨

O you who have believed, what is [the matter] with you that, when you are told to go forth in the cause of Allah, you adhere heavily to the earth? Are you satisfied with the life of this world rather than the Hereafter? But what is the enjoyment of worldly life compared to the Hereafter except a [very] little.

At-Taubah 9:39

إِلَّا تَنفِرُواْ يُعَذِّبۡكُمۡ عَذَابًا أَلِيمٗا وَيَسۡتَبۡدِلۡ قَوۡمًا غَيۡرَكُمۡ وَلَا تَضُرُّوهُ شَيۡـٔٗاۗ وَٱللَّهُ عَلَىٰ كُلِّ شَيۡءٖ قَدِيرٌ ٣٩

If you do not go forth, He will punish you with a painful punishment and will replace you with another people, and you will not harm Him at all. And Allah is over all things competent.

At-Taubah 9:41

ٱنفِرُواْ خِفَافٗا وَثِقَالٗا وَجَٰهِدُواْ بِأَمۡوَٰلِكُمۡ وَأَنفُسِكُمۡ فِي سَبِيلِ ٱللَّهِۚ ذَٰلِكُمۡ خَيۡرٞ لَّكُمۡ إِن كُنتُمۡ تَعۡلَمُونَ ٤١

Go forth, whether light or heavy, and strive with your wealth and your lives in the cause of Allah. That is better for you, if you only knew.
