Verse 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

It is not befitting for the dwellers of Medina and the Arabs who live in its suburbs to abandon the messenger of God, nor shall they give priority to themselves over him. This is because indeed neither thirst nor hardship nor hunger that they suffer in the cause of God nor taking a single step to enrage the unfaithful nor inflicting any hardship on the enemy that is not recorded as a good deed. Indeed God will never put to waste the reward for the do-gooders.
