Sura al-Baqara 2:143

وَكَذَٰلِكَ جَعَلْنَٰكُمْ أُمَّةً وَسَطًا لِّتَكُونُوا۟ شُهَدَآءَ عَلَى ٱلنَّاسِ وَيَكُونَ ٱلرَّسُولُ عَلَيْكُمْ شَهِيدًا وَمَا جَعَلْنَا ٱلْقِبْلَةَ ٱلَّتِى كُنتَ عَلَيْهَآ إِلَّا لِنَعْلَمَ مَن يَتَّبِعُ ٱلرَّسُولَ مِمَّن يَنقَلِبُ عَلَىٰ عَقِبَيْهِ وَإِن كَانَتْ لَكَبِيرَةً إِلَّا عَلَى ٱلَّذِينَ هَدَى ٱللَّـهُ وَمَا كَانَ ٱللَّـهُ لِيُضِيعَ إِيمَٰنَكُمْ إِنَّ ٱللَّـهَ بِٱلنَّاسِ لَرَءُوفٌ رَّحِيمٌ

wa-ka-dhālika jaʿalnākum ummatan wasaṭan li-takūnū shuhadāʾa ʿalā l-nāsi wa-yakūna l-rasūlu ʿalaykum shahīdan wa-mā jaʿalnā l-qiblata allatī kunta ʿalayhā illā linaʿlama man yattabiʿu l-rasūla mimman yanqalibu ʿalā ʿaqibayhi wa-in kānat la-kabīratan illā ʿalā lladhīna hadā allāhu wa-mā kāna allāhu li-yuḍīʿa īmānakum inna allāha bil-nāsi la-raʾūfun raḥīmun

Thus, have We made of you an Ummat justly balanced, that ye might be witnesses over the nations, and the Messenger a witness over yourselves; and We appointed the Qibla to which thou wast used, only to test those who followed the Messenger from those who would turn on their heels (From the Faith). Indeed it was (A change) momentous, except to those guided by Allah. And never would Allah Make your faith of no effect. For Allah is to all people Most surely full of kindness, Most Merciful.

Sura Āl-ʿImrān 3:171

يَسْتَبْشِرُونَ بِنِعْمَةٍ مِّنَ ٱللَّـهِ وَفَضْلٍ وَأَنَّ ٱللَّـهَ لَا يُضِيعُ أَجْرَ ٱلْمُؤْمِنِينَ

yastabshirūna biniʿmatin mina allāhi wa-faḍlin wa-anna allāha lā yuḍīʿu ajra l-muʾminīna

They glory in the Grace and the bounty from Allah, and in the fact that Allah suffereth not the reward of the Faithful to be lost (in the least).

Sura al-Tawbah 9:120

مَا كَانَ لِأَهْلِ ٱلْمَدِينَةِ وَمَنْ حَوْلَهُم مِّنَ ٱلْأَعْرَابِ أَن يَتَخَلَّفُوا۟ عَن رَّسُولِ ٱللَّـهِ وَلَا يَرْغَبُوا۟ بِأَنفُسِهِمْ عَن نَّفْسِهِۦ ذَٰلِكَ بِأَنَّهُمْ لَا يُصِيبُهُمْ ظَمَأٌ وَلَا نَصَبٌ وَلَا مَخْمَصَةٌ فِى سَبِيلِ ٱللَّـهِ وَلَا يَطَـُٔونَ مَوْطِئًا يَغِيظُ ٱلْكُفَّارَ وَلَا يَنَالُونَ مِنْ عَدُوٍّ نَّيْلًا إِلَّا كُتِبَ لَهُم بِهِۦ عَمَلٌ صَٰلِحٌ إِنَّ ٱللَّـهَ لَا يُضِيعُ أَجْرَ ٱلْمُحْسِنِينَ

mā kāna li-ahli l-madīnati wa-man ḥawlahum mina l-aʿrābi an yatakhallafū ʿan rrasūli allāhi wa-lā yarghabū bi-anfusihim ʿan nafsihi dhālika bi-annahum lā yuṣībuhum ẓamaʾun wa-lā naṣabun wa-lā makhmaṣatun fī sabīli allāhi wa-lā yaṭaʾūna mawṭian yaghīẓu l-kuffāra wa-lā yanālūna min ʿadūwin naylan illā kutiba lahum bihi ʿamalun ṣāliḥun inna allāha lā yuḍīʿu ajra l-muḥsinīna

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;-

Sura Hūd 11:115

وَٱصْبِرْ فَإِنَّ ٱللَّـهَ لَا يُضِيعُ أَجْرَ ٱلْمُحْسِنِينَ

wa-iṣbir fa-inna allāha lā yuḍīʿu ajra l-muḥsinīna

And be steadfast in patience; for verily Allah will not suffer the reward of the righteous to perish.

Sura Yūsuf 12:90

قَالُوٓا۟ أَءِنَّكَ لَأَنتَ يُوسُفُ قَالَ أَنَا۠ يُوسُفُ وَهَٰذَآ أَخِى قَدْ مَنَّ ٱللَّـهُ عَلَيْنَآ إِنَّهُۥ مَن يَتَّقِ وَيَصْبِرْ فَإِنَّ ٱللَّـهَ لَا يُضِيعُ أَجْرَ ٱلْمُحْسِنِينَ

qālū a-innaka la-anta yūsufu qalā anā yūsufu wa-hādhā akhī qad manna allāhu ʿalaynā innahu man yattaqi wa-yaṣbir fa-inna allāha lā yuḍīʿu ajra l-muḥsinīna

They said: "Art thou indeed Joseph?" He said, "I am Joseph, and this is my brother: Allah has indeed been gracious to us (all): behold, he that is righteous and patient,- never will Allah suffer the reward to be lost, of those who do right."

Sura Maryam 19:59

فَخَلَفَ مِنۢ بَعْدِهِمْ خَلْفٌ أَضَاعُوا۟ ٱلصَّلَوٰةَ وَٱتَّبَعُوا۟ ٱلشَّهَوَٰتِ فَسَوْفَ يَلْقَوْنَ غَيًّا

fa-khalafa min baʿdihim khalfun aḍāʿū l-ṣalāta wa-ittabaʿū l-shahawāti fa-sawfa yalqawna ghayyan

But after them there followed a posterity who missed prayers and followed after lusts soon, then, will they face Destruction,-
