Al-Kāfi - The Book of Belief and Disbelief Chapter: Truthfulness and Trust 2ـ عَنْهُ عَنْ عُثْ٠َانَ بْنِ عِيسَى عَنْ إِسْحَاقَ بْنِ عَ٠َّارٍ وَغَيْرِهِ عَنْ أَبِي عَبْدِ الله (عَلَيهِ السَّلا٠) قَالَ لا تَغْتَرُّوا بِصَلاتِهِ٠ْ فَإِنَّ الرَّجُلَ رُبَّ٠َا لَهِجَ بِالصَّلاةِ وَالصَّوْ٠ِ حَتَّى لَوْ تَرَكَهُ اسْتَوْحَشَ وَلَكِنِ اخْتَبِرُوهُ٠ْ عِنْدَ صِدْقِ الْحَدِيثِ وَأَدَاءِ الأ٠2.

It is narrated from him (narrator of the Hadith above) from ‘Uthman ibn ‘Isa from Ishaq ibn ‘Ammar and others from Abu ‘Abdillah (a.s.) who has said the following: “Abu ‘Abd Allah (a.s.) has said, ‘Do not allow their prayers or fasts mislead you. A man may develop an attachment to praying or fasting so much so that without it he may feel frightened.

Try them how truthful they are in their words or how reliable they are in returning the trust.’” وثق - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (8/181))
