Chapter on Hoarding and Pricing
Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 2|Chapter 18
وَ قِيلَ لِلنَّبِيِّ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ لَوْ سَعَّرْتَ لَنَا سِعْراً فَإِنَّ اَلْأَسْعَارَ تَزِيدُ وَ تَنْقُصُ فَقَالَ عَلَيْهِ اَلسَّلاَمُ "مَا كُنْتُ لِأَلْقَى اَللَّهَ تَعَالَى بِبِدْعَةٍ لَمْ يُحَدِّثْ إِلَيَّ فِيهَا شَيْئاً فَدَعُوا عِبَادَ اَللَّهِ يَأْكُلُ بَعْضُهُمْ مِنْ بَعْضٍ وَ إِذَا اُسْتُنْصِحْتُمْ فَانْصَحُوا".
It was said to the Prophet, peace and blessings be upon him and his family: "Would you set a fixed price for us, for prices rise and fall?" The Prophet صلى الله عليه وعلى آله وسلم replied: "I would not meet Allah سبحانه وتعالى, the Exalted, with an innovation about which He سبحانه وتعالى has revealed nothing to me. So leave the servants of Allah سبحانه وتعالى to benefit from one another. And if you are consulted for advice, then give sincere advice."
