Ata bin Abi Rabah says: I asked Sayyiduna Abdullah bin Umar (may Allah be pleased with them both): Were you present with the Prophet (peace be upon him) at the Pledge of Ridwan? He said: Yes! I asked: What were you wearing? He said: A cotton shirt, a padded coat, a sheet, and a sword. And I saw Nu'man bin Muqarrin standing over the head of the Prophet (peace be upon him). The branches of the tree were rising above the head of the Prophet (peace be upon him) and people were pledging allegiance to the Prophet (peace be upon him).
