فَاَثَابَهُمُ اللّٰهُ بِمَا قَالُوۡا جَنّٰتٍ تَجۡرِىۡ مِنۡ تَحۡتِهَا الۡاَنۡهٰرُ خٰلِدِيۡنَ فِيۡهَا ؕ وَذٰلِكَ جَزَآءُ الۡمُحۡسِنِيۡنَ(المائدة :85)
Faathabahumu Allahu bima qaloo jannatin tajree min tahtiha alanharu khalideena feeha wathalika jazao almuhsineena
Sahih International:
So Allah rewarded them for what they said with gardens [in Paradise] beneath which rivers flow, wherein they abide eternally. And that is the reward of doers of good.
مَا كَانَ لِاَهۡلِ الۡمَدِيۡنَةِ وَمَنۡ حَوۡلَهُمۡ مِّنَ الۡاَعۡرَابِ اَنۡ يَّتَخَلَّفُوۡا عَنۡ رَّسُوۡلِ اللّٰهِ وَ لَا يَرۡغَبُوۡا بِاَنۡفُسِهِمۡ عَنۡ نَّـفۡسِهٖ ؕ ذٰ لِكَ بِاَنَّهُمۡ لَا يُصِيۡبُهُمۡ ظَمَاٌ وَّلَا نَصَبٌ وَّلَا مَخۡمَصَةٌ فِىۡ سَبِيۡلِ اللّٰهِ وَلَا يَطَـُٔــوۡنَ مَوۡطِئًا يَّغِيۡظُ الۡكُفَّارَ وَلَا يَنَالُوۡنَ مِنۡ عَدُوٍّ نَّيۡلاً اِلَّا كُتِبَ لَهُمۡ بِهٖ عَمَلٌ صَالِحٌ ؕ اِنَّ اللّٰهَ لَا يُضِيۡعُ اَجۡرَ الۡمُحۡسِنِيۡنَۙ(التوبة :120)
Ma kana liahli almadeenati waman hawlahum mina ala'rabi an yatakhallafoo 'an rasooli Allahi wala yarghaboo bianfusihim 'an nafsihi thalika biannahum la yuseebuhum thamaon wala nasabun wala makhmasatun fee sabeeli Allahi wala yataoona mawtian yagheethu alkuffara wala yanaloona min 'aduwwin naylan illa kutiba lahum bihi 'amalun salihun inna Allaha la yudee'u ajra almuhsineena
Sahih International:
It was not [proper] for the people of Madinah and those surrounding them of the bedouins that they remain behind after [the departure of] the Messenger of Allah 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 Allah, nor do they tread on any ground that enrages the disbelievers, nor do they inflict upon an enemy any infliction but that is registered for them as a righteous deed. Indeed, Allah does not allow to be lost the reward of the doers of good.
وَاصۡبِرۡ فَاِنَّ اللّٰهَ لَا يُضِيۡعُ اَجۡرَ الۡمُحۡسِنِيۡنَ(هود :115)
Waisbir fainna Allaha la yudee'u ajra almuhsineena
Sahih International:
And be patient, for indeed, Allah does not allow to be lost the reward of those who do good.
اِنَّ الَّذِيۡنَ اٰمَنُوۡا وَعَمِلُوا الصّٰلِحٰتِ اِنَّا لَا نُضِيۡعُ اَجۡرَ مَنۡ اَحۡسَنَ عَمَلًا(الكهف :30)
Inna allatheena amanoo wa'amiloo alssalihati inna la nudee'u ajra man ahsana 'amalan
Sahih International:
Indeed, those who have believed and done righteous deeds - indeed, We will not allow to be lost the reward of any who did well in deeds.
