وَ رُوِيَ عَنْ أَبِي حَمْزَةَ اَلثُّمَالِيِّ عَنْ عَلِيِّ بْنِ اَلْحُسَيْنِ عَلَيْهِمَا اَلسَّلاَمُ قَالَ: "إِنَّ اَللَّهَ تَبَارَكَ وَ تَعَالَى وَكَّلَ بِالسِّعْرِ مَلَكاً يُدَبِّرُهُ بِأَمْرِهِ".
It is narrated by Abu Hamzah Al-Thumali, that Imam Ali ibn Al-Hussain عليه السلام, who said: "Indeed, Allah سبحانه وتعالى, the Blessed and Exalted, has appointed an angel to regulate prices by His command."
