Surah 9. Al-Tawba
Ayah 119 - 121
119 يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ ٱتَّقُوا۟ ٱللَّهَ وَكُونُوا۟ مَعَ ٱلصَّـٰدِقِينَ
120 مَا كَانَ لِأَهْلِ ٱلْمَدِينَةِ وَمَنْ حَوْلَهُم مِّنَ ٱلْأَعْرَابِ أَن يَتَخَلَّفُوا۟ عَن رَّسُولِ ٱللَّهِ وَلَا يَرْغَبُوا۟ بِأَنفُسِهِمْ عَن نَّفْسِهِۦ ۚ ذَٰلِكَ بِأَنَّهُمْ لَا يُصِيبُهُمْ ظَمَأٌ وَلَا نَصَبٌ وَلَا مَخْمَصَةٌ فِى سَبِيلِ ٱللَّهِ وَلَا يَطَـُٔونَ مَوْطِئًا يَغِيظُ ٱلْكُفَّارَ وَلَا يَنَالُونَ مِنْ عَدُوٍّ نَّيْلًا إِلَّا كُتِبَ لَهُم بِهِۦ عَمَلٌ صَـٰلِحٌ ۚ إِنَّ ٱللَّهَ لَا يُضِيعُ أَجْرَ ٱلْمُحْسِنِينَ
121 وَلَا يُنفِقُونَ نَفَقَةً صَغِيرَةً وَلَا كَبِيرَةً وَلَا يَقْطَعُونَ وَادِيًا إِلَّا كُتِبَ لَهُمْ لِيَجْزِيَهُمُ ٱللَّهُ أَحْسَنَ مَا كَانُوا۟ يَعْمَلُونَ
[119-121] O Believers, fear Allah and be with those who are Truthful. It did not behoove the people of Al-Madinah and the Bedouins, dwelling around, to abandon Allah's Messenger and stay at home in order to safeguard their own interests, in utter disregard of him. For, every hardship like thirst, hunger and any other physical ordeal they suffer in the Way of Allah, and every step they take on that Way which enrages the unbelievers, and every act of wreaking vengeance upon the enemies of the truth, is credited in their favor with a good deed for each: surely Allah does not let go unrewarded any deed of the righteous people. Likewise, whatever they spend (in the Way of Allah), be it little or much, and whichever valley they traverse (for Jihad), is credited to their account so that Allah may reward them for the good deeds they did.
