Sura al-Tawbah 9:120

مَا كَانَ لِأَهْلِ ٱلْمَدِينَةِ وَمَنْ حَوْلَهُم مِّنَ ٱلْأَعْرَابِ أَن يَتَخَلَّفُوا۟ عَن رَّسُولِ ٱللَّـهِ وَلَا يَرْغَبُوا۟ بِأَنفُسِهِمْ عَن نَّفْسِهِۦ ذَٰلِكَ بِأَنَّهُمْ لَا يُصِيبُهُمْ ظَمَأٌ وَلَا نَصَبٌ وَلَا مَخْمَصَةٌ فِى سَبِيلِ ٱللَّـهِ وَلَا يَطَـُٔونَ مَوْطِئًا يَغِيظُ ٱلْكُفَّارَ وَلَا يَنَالُونَ مِنْ عَدُوٍّ نَّيْلًا إِلَّا كُتِبَ لَهُم بِهِۦ عَمَلٌ صَٰلِحٌ إِنَّ ٱللَّـهَ لَا يُضِيعُ أَجْرَ ٱلْمُحْسِنِينَ

It was not fitting for the people of Medina and the Bedouin Arabs of the neighbourhood, to refuse to follow Allah's Messenger, nor to prefer their own lives to his: because nothing could they suffer or do, but was reckoned to their credit as a deed of righteousness,- whether they suffered thirst, or fatigue, or hunger, in the cause of Allah, or trod paths to raise the ire of the Unbelievers, or received any injury whatever from an enemy: for Allah suffereth not the reward to be lost of those who do good;-
