Chapter 135 | Hardheartedness
1ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عَمْرِو بْنِ عُثْمَانَ عَنْ عَلِيِّ بْنِ عِيسَى رَفَعَهُ قَالَ فِيمَا نَاجَى الله عَزَّ وَجَلَّ بِهِ مُوسَى (عَلَيهِ السَّلام) يَا مُوسَى لا تُطَوِّلْ فِي الدُّنْيَا أَمَلَكَ فَيَقْسُوَ قَلْبُكَ وَالْقَاسِي الْقَلْبِ مِنِّي بَعِيدٌ.
1. A number of our people have narrated from Ahmad ibn Muhammad from ‘Amr ibn ‘Uthman from Ali ibn ‘Isa in a marfu’ manner has said the following: “It is in the conversations of Moses with Allah, the Most Majestic, the Most Holy, ‘O Moses, do not prolong your hopes in the world; it hardens your heart and the hardhearted people are far away from Me.’”
