(السُّودُ فِي النَّسِيئَةِ وَلَيْسَ فِي النَّقْدِ)
(Usury is in credit transactions, not in cash)
Hadith 2824
عَنْ أُسَامَةُ بْنُ زَيْدٍ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «الرِّبَا فِي النَّسِيئَةِ» . وَفِي رِوَايَةٍ قَالَ: «لَا رِبًا فِيمَا كَانَ يدا بيد»
Usama b. Zaid reported the Prophet as saying, "Credit involves usury.” In a version he said, "There is no usury when payment is made on the spot.” (Bukhari and Muslim.)
