2ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ حَمَّادِ بْنِ عُثْمَانَ عَنِ الْمُعَلَّى بْنِ خُنَيْسٍ قَالَ قُلْتُ لابِي عَبْدِ الله (عَلَيْهِ السَّلام) يَوْماً جُعِلْتُ فِدَاكَ ذَكَرْتُ آلَ فُلانٍ وَمَا هُمْ فِيهِ مِنَ النَّعِيمِ فَقُلْتُ لَوْ كَانَ هَذَا إِلَيْكُمْ لَعِشْنَا مَعَكُمْ فَقَالَ هَيْهَاتَ يَا مُعَلَّى أَمَا وَالله أَنْ لَوْ كَانَ ذَاكَ مَا كَانَ إِلا سِيَاسَةَ اللَّيْلِ وَسِيَاحَةَ النَّهَارِ وَلُبْسَ الْخَشِنِ وَأَكْلَ الْجَشِبِ فَزُوِيَ ذَلِكَ عَنَّا فَهَلْ رَأَيْتَ ظُلامَةً قَطُّ صَيَّرَهَا الله تَعَالَى نِعْمَةً إِلا هَذِهِ.

2. Ali ibn Ibrahim has narrated from his father from ibn abu ‘Umayr from Hammad ibn ‘Uthman from Mu‘alla ibn Khunays who has said the following. “One day I said to abu ‘Abdallah (a.s.), may Allah take my soul in service for your cause, I thought of the descendants of so and so (‘Abbasside) and the wealth they have at their disposal. Then I wished that had such wealth been at your disposal we would have lived with you prosperously.” The Imam (a.s.) said, “Never O Mu‘alla, by Allah, had it been as you wished, there would have been nothing but hard labor of protections at nights and strenuous work during the days, coarse garments and tasteless food. Thus, it is kept away from us. Have you ever seen a usurpation that Allah, the Most High, would cause to become a blessing except this?”
