divine compensation

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 was not [proper] for the people of Madīnah and those surrounding them of the bedouins that they remain behind after [the departure of] the Messenger of Allāh or that they prefer themselves over his self. That is because they are not afflicted by thirst or fatigue or hunger in the cause of Allāh, nor do they tread on any ground that enrages the disbelievers, nor do they inflict upon an enemy any infliction but that it is registered for them as a righteous deed. Indeed, Allāh does not allow to be lost the reward of the doers of good.

فَإِن تَوَلَّيْتُمْ فَمَا سَأَلْتُكُم مِّنْ أَجْرٍ ۖ إِنْ أَجْرِىَ إِلَّا عَلَى ٱللَّهِ ۖ وَأُمِرْتُ أَنْ أَكُونَ مِنَ ٱلْمُسْلِمِينَ

And if you turn away [from my advice] - then no payment have I asked of you. My reward is only from Allāh, and I have been commanded to be of the Muslims [i.e., those who submit to Allāh]."

وَٱلَّذِينَ هَاجَرُوا۟ فِى ٱللَّهِ مِنۢ بَعْدِ مَا ظُلِمُوا۟ لَنُبَوِّئَنَّهُمْ فِى ٱلدُّنْيَا حَسَنَةً ۖ وَلَأَجْرُ ٱلْـَٔاخِرَةِ أَكْبَرُ ۚ لَوْ كَانُوا۟ يَعْلَمُونَ

And those who emigrated for [the cause of] Allāh after they had been wronged - We will surely settle them in this world in a good place; but the reward of the Hereafter is greater, if only they could know.

عَسَىٰ رَبُّنَآ أَن يُبْدِلَنَا خَيْرًا مِّنْهَآ إِنَّآ إِلَىٰ رَبِّنَا رَٰغِبُونَ

Perhaps our Lord will substitute for us [one] better than it. Indeed, we are toward our Lord desirous."
