Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates from Sayyiduna Umar bin al-Khattab (may Allah be pleased with him), regarding the story of the two women who had banded together (against the Prophet), that he said: I came to the upper room where the Messenger of Allah (peace and blessings be upon him) was. I said to a black servant boy of his (peace and blessings be upon him): Ask permission for Umar. The servant went in and spoke to the Messenger of Allah (peace and blessings be upon him), then came back to me and said: I mentioned you to the Messenger of Allah (peace and blessings be upon him), and he (peace and blessings be upon him) remained silent. I went back and sat with the group who were by the pulpit. Then what I was feeling overcame me, so I said to the servant again: Ask permission for Umar. The servant went in and mentioned it before him (peace and blessings be upon him), and he (peace and blessings be upon him) remained silent. He said: When I turned to go back, the servant called me from behind: The Messenger of Allah (peace and blessings be upon him) has given you permission. I went in, and the Messenger of Allah (peace and blessings be upon him) was lying on a mat woven of palm strips. There was no bedding between him and it. The marks of the mat were on his (peace and blessings be upon him) side. He (peace and blessings be upon him) was reclining on a leather pillow stuffed with palm fibre.
