Hadith #1

1ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ عِيسَى عَنِ ابْنِ مَحْبُوبٍ عَنْ حَمَّادٍ عَنْ حُمَيْدٍ وَجَابِرٍ الْعَبْدِيِّ قَالَ قَالَ أَمِيرُ الْمُؤْمِنِينَ (عَلَيْهِ السَّلام) إِنَّ الله جَعَلَنِي إِمَاماً لِخَلْقِهِ فَفَرَضَ عَلَيَّ التَّقْدِيرَ فِي نَفْسِي وَمَطْعَمِي وَمَشْرَبِي وَمَلْبَسِي كَضُعَفَاءِ النَّاسِ كَيْ يَقْتَدِيَ الْفَقِيرُ بِفَقْرِي وَلا يُطْغِيَ الْغَنِيَّ غِنَاهُ.

1. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa from ibn Mahbub from Hammad from Humayd and Jabir al-‘Abdi who has said the following. “Amir al-Mu’minin (a.s.) has said, ‘Allah has appointed me the Imam for His creation, Therefore, He made it obligatory for me to discipline myself in the matters of food, drinks and clothes to the level of the very weak ones of the people so that the poor follow my poverty and the rich would not become rebellious because of his riches.’”
