The Book Pertaining to the Excellent Qualities of the Holy Prophet (may Peace be upon them) and His Companions (Kitab Al-Fadail)
Book Number: 030 / Hadith Number: 5732
Jabir b. 'Abdullah reported: When Allah's Apostle (may peace be upon him) died, there came to Abfi Bakr wealth from al-'Ala' b. al-Hadrami. Abu Bakr said: He to whom Allah's Apostle (may peace be upon him) owed any debt or held out any promise should come to us; the rest of the hadith is the same.
