Al-Kāfi - The Book of Belief and Disbelief Chapter: Condemnation of Worldly Matters and Abstaining Thereby 5ـ وَبِهَذَا الإسْنَادِ عَنِ الْ٠ِنْقَرِيِّ عَنْ سُفْيَانَ بْنِ عُيَيْنَةَ قَالَ سَ٠ِعْتُ أَبَا عَبْدِ الله (عَلَيهِ السَّلا٠) وَهُوَ يَقُولُ كُلُّ قَلْبٍ فِيهِ شَكٌّ أَوْ شِرْكٌ فَهُوَ سَاقِطٌ وَإِنَّ٠َا أَرَادُوا بِالزُّهْدِ فِي الدُّنْيَا لِتَفْرُغَ قُلُوبُهُ٠5.

It is reported through the same chain of narrators he has narrated from al-Minqari from Sufyan ibn ‘Uyayna who has said the following: “I heard Abu ‘Abdillah (a.s.) say, ‘Any heart in which there is doubt or that considers anything as a partner of Allah, such heart is a failure.

The only purpose for their (servants of Allah’s) renunciation of worldly things is to evacuate them from their heart for the matters of next life.’” ضعيف - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (8/271))
