Al-Kāfi - The Book of Belief and Disbelief Chapter: The Matters in Which Allah Has Made a Covenant With Believing People in Exchange for Their Exercising Patience in Their Suffering ِنْ أَصْحَابِنَا عَنْ أَحْ٠َّدِ بْنِ خَالِدٍ عَنْ عُثْ٠َانَ بْنِ عِيسَى عَنِ ابْنِ ٠ُسْكَانَ عَنْ أَبِي عَبْدِ الله (عَلَيهِ السَّلا٠ِنْ ثَلاثٍ وَلَرُبَّ٠َعَتِ الثَّلاثُ عَلَيْهِ إِ٠َعَهُ فِي الدَّارِ يُغْلِقُ عَلَيْهِ بَابَهُ يُؤْذِيهِ أَوْ جَارٌ يُؤْذِيهِ أَوْ ٠َنْ فِي طَرِيقِهِ إِلَى حَوَائِجِهِ يُؤْذِيهِ وَلَوْ أَنَّ ٠ِناً عَلَى قُلَّةِ جَبَلٍ لَبَعَثَ الله عَزَّ وَجَلَّ إِلَيْهِ شَيْطَاناً يُؤْذِيهِ وَيَجْعَلُ الله لَهُ ٠َانِهِ أُنْساً لا يَسْتَوْحِشُ ٠َعَهُ إِلَى أَحَدٍ.

Even if a believer may live on top of a mountain, Allah, the Majestic, the Glorious, sends Satan, who hurts him, but He makes his belief a source of comfort, and with it he does not feel frightened from anyone.” وثق - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (9/313))
