I was reading a (poorly written) essay recently, wherein a hadith was mentioned but not fully quoted. Allegedly, the classical fuqaha used it to forbid bay' al-kali bil-kali (Selling of debts for debts).
Beyond that, all I know is that it was reported by Ibn 'Umar, as related by al-Tabrani (sic).
What does this hadith say, and how authentic is it?
عن ابن عمر - رضي الله عنهما - ، أن النبي صلى الله عليه وآله وسلم نهى عن بيع الكالئ بالكالئ
The Prophet prohibited the selling of debts for debts
Note: One of the persons mentioned in the sanad of this Hadith is (موسى بن عقبة) and that is a mistake, for the narrator actually is (موسى بن عبيدة).
As for the authenticity of the Hadith, it is Da'eef.
