10ـ سَهْلٌ عَنِ الْحَسَنِ بْنِ عَلِيٍّ عَنْ فُضَيْلِ بْنِ مُيَسِّرٍ قَالَ كُنَّا عِنْدَ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) فَجَاءَ رَجُلٌ فَشَكَا إِلَيْهِ مُصِيبَةً أُصِيبَ بِهَا فَقَالَ لَهُ أَبُو عَبْدِ الله (عَلَيْهِ الْسَّلام) أَمَا إِنَّكَ إِنْ تَصْبِرْ تُؤْجَرْ وَإِلاَّ تَصْبِرْ يَمْضِ عَلَيْكَ قَدَرُ الله الَّذِي قَدَّرَ عَلَيْكَ وَأَنْتَ مَأْزُورٌ.
10. Sahl has narrated from al-Hassan ibn Ali from al-Fudayl ibn Muyassir who has said the following: “We were in the presence of abu ‘Abd Allah (a.s.), when a man came and complained before him about a misfortune that he had suffered. Abu ‘Abd Allah (a.s.), said, ‘If you exercise patience, you will be rewarded and if you do not exercise patience, Allah’s system of working of things will apply to you without change and you will be counted a sinner.’”
