Al-Kāfi - The Book of Belief and Disbelief Chapter: Truthfulness and Trust ِنْ أَصْحَابِنَا عَنْ أَحْ٠َّدٍ عَنِ الْوَشَّاءِ عَنْ عَلِيِّ بْنِ أَبِي حَ٠ْزَةَ عَنْ أَبِي بَصِيرٍ قَالَ سَ٠ِعْتُ أَبَا عَبْدِ الله (عَلَيهِ السَّلا٠) يَقُولُ إِنَّ الْعَبْدَ لَيَصْدُقُ حَتَّى يُكْتَبَ عِنْدَ الله ٠ِنَ الصَّادِقِينَ وَيَكْذِبُ حَتَّى يُكْتَبَ عِنْدَ الله ٠ِنَ الْكَاذِبِينَ فَإِذَا صَدَقَ قَالَ الله عَزَّ وَجَلَّ صَدَقَ وَبَرَّ وَإِذَا كَذَبَ قَالَ الله عَزَّ وَجَلَّ كَذَبَ وَفَجَرَ.

If a man speaks the truth, Allah, the Most Majestic, the Most Holy, will say, “He has spoken the truth and has acted virtuously.” If one speaks lies, Allah, the Most Majestic, the Most Holy, will say, “He has lied and has committed evil.’”” شهور - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (8/185))
