أَخْبَرَنَا مُحَمَّدُ بْنُ بَشَّارٍ، قَالَ حَدَّثَنَا عَبْدُ الرَّحْمَنِ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ مُوسَى أَبِي شِهَابٍ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، أَنَّهُ كَانَ لاَ يَرَى بَأْسًا وَإِنْ كَانَ مِنْ قَرْضٍ .
It was narrated from Saeed bin Jubair that: he did not see anything wrong with it even if it was on credit.
