The Quran root ج ه د j-h-d

إِنَّ الَّذِينَ آمَنُوا وَالَّذِينَ هَاجَرُوا وَجَاهَدُوا فِي سَبِيلِ اللَّهِ أُولَٰئِكَ يَرْجُونَ رَحْمَتَ اللَّهِ وَاللَّهُ غَفُورٌ رَّحِيمٌ ٢١٨

وَجَاهَدُوا wajāhadū · and strove

Indeed, those who have believed and those who have emigrated and fought in the cause of Allāh - those expect the mercy of Allāh. And Allāh is Forgiving and Merciful. (Surah Al-Baqarah, 2:218)

أَمْ حَسِبْتُمْ أَن تَدْخُلُوا الْجَنَّةَ وَلَمَّا يَعْلَمِ اللَّهُ الَّذِينَ جَاهَدُوا مِنكُمْ وَيَعْلَمَ الصَّابِرِينَ ١٤٢

جَاهَدُوا jāhadū · strove hard

Or do you think that you will enter Paradise while Allāh has not yet made evident those of you who fight in His cause and made evident those who are steadfast? (Surah Ali 'Imran, 3:142)

وَيَقُولُ الَّذِينَ آمَنُوا أَهَٰؤُلَاءِ الَّذِينَ أَقْسَمُوا بِاللَّهِ جَهْدَ أَيْمَانِهِمْ إِنَّهُمْ لَمَعَكُمْ حَبِطَتْ أَعْمَالُهُمْ فَأَصْبَحُوا خَاسِرِينَ ٥٣

جَهْدَ jahda · strongest

And those who believe will say, "Are these the ones who swore by Allāh their strongest oaths that indeed they were with you?" Their deeds have become worthless, and they have become losers. (Surah Al-Ma'idah, 5:53)

لَّا يَسْتَوِي الْقَاعِدُونَ مِنَ الْمُؤْمِنِينَ غَيْرُ أُولِي الضَّرَرِ وَالْمُجَاهِدُونَ فِي سَبِيلِ اللَّهِ بِأَمْوَالِهِمْ وَأَنفُسِهِمْ فَضَّلَ اللَّهُ الْمُجَاهِدِينَ بِأَمْوَالِهِمْ وَأَنفُسِهِمْ عَلَى الْقَاعِدِينَ دَرَجَةً وَكُلًّا وَعَدَ اللَّهُ الْحُسْنَىٰ وَفَضَّلَ اللَّهُ الْمُجَاهِدِينَ عَلَى الْقَاعِدِينَ أَجْرًا عَظِيمًا ٩٥

وَالْمُجَاهِدُونَ wal-mujāhidūna · and the ones who strive

Not equal are those believers remaining [at home] - other than the disabled - and the mujāhideen, [who strive and fight] in the cause of Allāh with their wealth and their lives. Allāh has preferred the mujāhideen through their wealth and their lives over those who remain [behind], by degrees. And to all [i.e., both] Allāh has promised the best [reward]. But Allāh has preferred the mujāhideen over those who remain [behind] with a great reward - (Surah An-Nisa, 4:95)

قُلْ إِن كَانَ آبَاؤُكُمْ وَأَبْنَاؤُكُمْ وَإِخْوَانُكُمْ وَأَزْوَاجُكُمْ وَعَشِيرَتُكُمْ وَأَمْوَالٌ اقْتَرَفْتُمُوهَا وَتِجَارَةٌ تَخْشَوْنَ كَسَادَهَا وَمَسَاكِنُ تَرْضَوْنَهَا أَحَبَّ إِلَيْكُم مِّنَ اللَّهِ وَرَسُولِهِ وَجِهَادٍ فِي سَبِيلِهِ فَتَرَبَّصُوا حَتَّىٰ يَأْتِيَ اللَّهُ بِأَمْرِهِ وَاللَّهُ لَا يَهْدِي الْقَوْمَ الْفَاسِقِينَ ٢٤

وَجِهَادٍ wajihādin · and striving

Say, [O Muḥammad], "If your fathers, your sons, your brothers, your wives, your relatives, wealth which you have obtained, commerce wherein you fear decline, and dwellings with which you are pleased are more beloved to you than Allāh and His Messenger and jihād [i.e., striving] in His cause, then wait until Allāh executes His command. And Allāh does not guide the defiantly disobedient people." (Surah At-Tawbah, 9:24)

الَّذِينَ يَلْمِزُونَ الْمُطَّوِّعِينَ مِنَ الْمُؤْمِنِينَ فِي الصَّدَقَاتِ وَالَّذِينَ لَا يَجِدُونَ إِلَّا جُهْدَهُمْ فَيَسْخَرُونَ مِنْهُمْ سَخِرَ اللَّهُ مِنْهُمْ وَلَهُمْ عَذَابٌ أَلِيمٌ ٧٩

جُهْدَهُمْ juh'dahum · their effort

Those who criticize the contributors among the believers concerning [their] charities and [criticize] the ones who find nothing [to spend] except their effort, so they ridicule them - Allāh will ridicule them, and they will have a painful punishment. (Surah At-Tawbah, 9:79)
