Maliks Muwatta Book 21, Hadith Number 51.

Section : Burial in One Grave by Necessity and Abu Bakr’s (PBUH), Carrying Out the Promise of the Messenger of Allah (PBUH), After the Death of the Messenger (PBUH).

Yahya related to me from Malik that Rabia ibn Abi Abd ar-Rahman said, “Property was sent to Abu Bakr as-Siddiq from Bahrayn. He said, ‘If someone had a promise or a pledge with the Messenger of Allah, may Allah bless him and grant him peace, let him come to me.’ So Jabir ibn Abdullah came to him, and he gave him three times as much of it as would fill both hands.'”
