Qurʾān Bukhārī Muslim Nasāʾī Abū Dāwūd Tirmidhī Ibn Mājah Mālik Aḥmad Dārimī Ḥākim Ibn Ḥibbān Ṭabarānī Nasāʾī's Kubrá Bayhaqī al-Luʾluʾ wa-al-Marjān Ibn Rajab's Fifty Riyāḍ al-Ṣāliḥīn Aḥmad's Zuhd Suyūṭī
quran:18:30 –

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.  

Truly those who believe and perform righteous deeds — indeed We do not leave the reward of those of good deeds to go to waste (this ˹last˺ sentence is the predicate of the ˹previous˺ inna’lladhīna, ‘truly those who’, and in it an overt identification ˹of the recipients of the reward˺ has replaced the ˹would-be˺ pronominalisation, in other words, it is ‘their reward’ ˹which shall not be left to go to waste˺, and We will reward them with what it ˹the reward of good-doers˺ comprises).
القرآن:١٨:٣٠ –

إِنَّ الَّذِينَ آمَنُوا وَعَمِلُوا الصَّالِحَاتِ إِنَّا لَا نُضِيعُ أَجْرَ مَنْ أَحْسَنَ عَمَلًا  

{إن الذين آمنوا وعملوا الصالحات إنا لا نضيع أجر من أحسن عملاً} الجملة خبر إن الذين وفيها إقامة الظاهر مقام المضمر والمعنى أجرهم أي نثيبهم بما تضمنه.
