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

‘Umar b. al-Khattab said

The last verse to be sent down was that on usury (Al-Qur’an 2:275) but God's Messenger was taken without having expounded it to us; so leave aside usury and whatever is doubtful. Ibn Majah and Darimi transmitted it.
