Ibn Jurayj relates from Futayr al-Ansari that the Messenger of Allah (peace and blessings be upon him) did not estimate the 'araya (palms given as gifts), nor did Abu Bakr and Umar (may Allah be pleased with them both).
Both of these are mursal, and a connected (mawsul) hadith has been narrated on this.
