عَنْ أُسَامَةُ بْنُ زَيْدٍ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «الرِّبَا فِي النَّسِيئَةِ» . وَفِي رِوَايَةٍ قَالَ: «لَا رِبًا فِيمَا كَانَ يدا بيد»

Abu Burda b. Abu Musa said

I came to Medina and met 'Abdallah b. Salam who said, "You are in a land in which usury is common, so when anyone owes you anything and presents you with a load of straw, or a load of barley, or a rope of lucerne grass, do not accept it for it is usury." Bukhari transmitted it.
