lazinesspatience
5- عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ ابْنِ فَضَّالٍ عَنْ سَمَاعَةَ بْنِ مِهْرَانَ عَنْ أَبِي الْحَسَنِ مُوسَى (عَلَيْهِ السَّلام) قَالَ إِيَّاكَ وَالْكَسَلَ وَالضَّجَرَ فَإِنَّكَ إِنْ كَسِلْتَ لَمْ تَعْمَلْ وَإِنْ ضَجِرْتَ لَمْ تُعْطِ الْحَقَّ.
5. A number of our people have narrated from Ahmad ibn Muhammad from ibn Faddal from Sama‘ah ibn Mehran from abu al-Hassan, Musa (a.s.), who has said the following: “Abu al-Hassan, Musa (a.s.), has said, ‘Beware of laziness and impatience; with laziness you do not work and with impatience you do not yield to the truth.”
