أَخْبَرَنَا عُثْمَانُ بْنُ عُمَرَ ، أَخْبَرَنَا إِسْرَائِيلُ ، عَنْ أَبِي إِسْحَاق ، عَنْ مَسْرُوقٍ ، عَنْ بِلَالٍ ، قَالَ : كَانَ عِنْدِي مُدُّ تَمْرٍ لِلنَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَوَجَدْتُ أَطْيَبَ مِنْهُ صَاعًا بِصَاعَيْنِ، فَاشْتَرَيْتُ مِنْهُ، فَأَتَيْتُ بِهِ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ، فَقَالَ :" مِنْ أَيْنَ لَكَ هَذَا يَا بِلَالُ؟ ".
قُلْتُ : اشْتَرَيْتُ صَاعًا بِصَاعَيْنِ.
قَالَ : " رُدَّهُ وَرُدَّ عَلَيْنَا تَمْرَنَا "

Othman bin Omar told us, Israel told us, on the authority of Abu Ishaq, on the authority of Masruq, on the authority of Bilal, he said: I had a mudd of dates for the Prophet, may God bless him and grant him peace. May God bless him and grant him peace. I found something better than it, one sa’ for two sa’s, so I bought it from him and brought it to the Prophet, may God’s prayers and peace be upon him, and he said: “Where did you get it from?” This, Bilal?
I said: I bought one sa' for two sa's.
He said: “Return him and give us our dates.”
