The explanation of His word, the Exalted: إِنَّ الَّذِينَ آمَنُوا وَعَمِلُوا الصَّالِحَاتِ لَهُمْ أَجْرٌ غَيْرُ مَمْنُونٍ ("Verily, those who believe and do righteous deeds: for them there is an unceasing reward") (41:8).
He, exalted is His mention, says: verily, those who held Allah and His Messenger to be true, and who acted in accordance with that which Allah and His Messenger commanded them, and who abstained from that which He forbade them — and that is the righteous deeds — لَهُمْ أَجْرٌ غَيْرُ مَمْنُونٍ ("for them there is an unceasing reward"). He says: for whoever does that there is a reward that is not diminished from that which He promised to give them as a reward.
The people of interpretation (ahl al-taʾwīl) have differed concerning the explanation of that, and I have already expounded that previously in a manner that makes it unnecessary to repeat it in this place. And indeed:
Muḥammad ibn al-Ḥusayn related to me, he said: Aḥmad ibn al-Mufaḍḍal related to us, he said: Asbāṭ related to us, on the authority of al-Suddī: لَهُمْ أَجْرٌ غَيْرُ مَمْنُونٍ ("for them there is an unceasing reward") — some of them said: not diminished. And others said: not as a favor cast in their faces.
ʿAlī related to me, he said: Abū Ṣāliḥ related to us, he said: Muʿāwiya related to me, on the authority of ʿAlī, on the authority of Ibn ʿAbbās, concerning His word أَجْرٌ غَيْرُ مَمْنُونٍ ("an unceasing reward"), he says: not diminished.
Muḥammad ibn ʿAmr related to me, he said: Abū ʿĀṣim related to us, he said: ʿĪsā related to us; and al-Ḥārith related to me, he said: al-Ḥasan related to us, he said: Warqāʾ related to us — both — on the authority of Ibn Abī Najīḥ, concerning His word لَهُمْ أَجْرٌ غَيْرُ مَمْنُونٍ ("for them there is an unceasing reward"), he said: reckoned.
