Surat At-Tawbah (119-120)

{يَا أَيُّهَا الَّذِينَ آمَنُواْ اتَّقُواْ اللّهَ وَكُونُواْ مَعَ الصَّادِقِينَ} (التوبة : 119)

119- O believers, beware of disobeying the command of Allah, avoid things which do not please Him, and abide by the truth to be truthful, to save yourselves of destruction so that Allah would grant you a way out of you troubles.

{مَا كَانَ لِأَهْلِ الْمَدِينَةِ وَمَنْ حَوْلَهُم مِّنَ الأَعْرَابِ أَن يَتَخَلَّفُواْ عَن رَّسُولِ اللّهِ وَلاَ يَرْغَبُواْ بِأَنفُسِهِمْ عَن نَّفْسِهِ ذَلِكَ بِأَنَّهُمْ لاَ يُصِيبُهُمْ ظَمَأٌ وَلاَ نَصَبٌ وَلاَ مَخْمَصَةٌ فِي سَبِيلِ اللّهِ وَلاَ يَطَؤُونَ مَوْطِئاً يَغِيظُ الْكُفَّارَ وَلاَ يَنَالُونَ مِنْ عَدُوٍّ نَّيْلاً إِلاَّ كُتِبَ لَهُم بِهِ عَمَلٌ صَالِحٌ إِنَّ اللّهَ لاَ يُضِيعُ أَجْرَ الْمُحْسِنِينَ} (التوبة : 120)

120- It was not proper for the people of Medina and those who were around them of Arabs to lag behind supporting the Messenger of Allah (peace be upon him) in the battle of Tabuk. Moreover, they should not have restrained from sacrificing their souls for him, but they should have suffered as he did. By lagging behind, they deprived themselves from a great reward. Indeed, the thirst, fatigue, or hunger —which those who participate in Jihad feel while obeying Allah, fighting His enemy by killing or capturing them, and gaining the war booty— shall be rewarded and Allah shall not waste their righteous actions in supporting His Religion.
