Surah At-Taubah (The Repentance), Verse 120

مَا كَانَ لِاَهْلِ الْمَدِیْنَةِ وَمَنْ حَوْلَهُمْ مِّنَ الْاَعْرَابِ اَنْ یَّتَخَلَّفُوْا عَنْ رَّسُوْلِ اللّٰهِ وَلَا یَرْغَبُوْا بِاَنْفُسِهِمْ عَنْ نَّفْسِهٖ ذٰلِكَ بِاَنَّهُمْ لَا یُصِیْبُهُمْ ظَمَاٌ وَّلَا نَصَبٌ وَّلَا مَخْمَصَةٌ فِیْ سَبِیْلِ اللّٰهِ وَلَا یَطَـُٔوْنَ مَوْطِئًا یَّغِیْظُ الْكُفَّارَ وَلَا یَنَالُوْنَ مِنْ عَدُوٍّ نَّیْلًا اِلَّا كُتِبَ لَهُمْ بِهٖ عَمَلٌ صَالِحٌ اِنَّ اللّٰهَ لَا یُضِیْعُ اَجْرَ الْمُحْسِنِیْنَ ۟

“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;-”
