4029 - وَ سَأَلَهُ مُحَمَّدُ بْنُ مُسْلِمٍ عَنِ الرَّجُلِ يَسْتَقْرِضُ مِنَ الرَّجُلِ قَرْضاً وَ يُعْطِيهِ الرَّهْنَ إِمَّا خَادِماً وَ إِمَّا آنِيَةً وَ إِمَّا ثِيَاباً فَيَحْتَاجُ إِلَى الشَّيْءِ مِنْ أَمْتِعَتِهِ فَيَسْتَأْذِنُهُ فِيهِ فَيَأْذَنُ لَهُ قَالَ إِنْ طَابَتْ نَفْسُهُ لَهُ فَلَا بَأْسَ قُلْتُ إِنَّ مَنْ عِنْدَنَا يَرْوُونَ أَنَّ كُلَّ قَرْضٍ جَرَّ مَنْفَعَةً فَهُوَ فَاسِدٌ فَقَالَ أَ وَ لَيْسَ خَيْرُ الْقَرْضِ مَا جَرَّ مَنْفَعَةً.
Hadith.4029 - Muhammad ibn Muslim asked him about a man who borrows a loan from another man and gives him collateral, either a servant, a vessel, or clothing.
Later, the borrower needs something from his belongings and seeks permission from the lender, who grants it.
Imam 
said: "If the lender willingly allows it, then there is no harm."
I said: "Those among us narrate that any loan that brings benefit is invalid."
Imam replied: "Isn't the best loan the one that brings benefit?"
