Sa'id bin al-Musayyib (may Allah have mercy on him) said that the Messenger of Allah (peace and blessings be upon him) said: "The pledge is not to be withheld from the one who pledged it. Its gain is his and its loss is his." In one narration the wording is: "The liability is on the one who pledged it; the gain will go to him and the loss will also be counted against him."

Ali (al-Daraqutni) said: Ziyad bin Sa'd is one of the trustworthy huffaz (hadith masters), and this is a hasan (good), connected chain.
The Shaykh said: Another narrator narrated it from Sufyan from Ziyad as mursal, and that is the mahfuz (preserved) version. Abu Amr al-Awza'i and Yunus bin Yazid al-Ayli narrated it from al-Zuhri from Ibn al-Musayyib as mursal, except that they made "Its gain is his and its loss is his" the words of Sa'id bin al-Musayyib. And Allah knows best.
