Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) said: I was with my father in the presence of the Prophet (peace and blessings be upon him), and with the Prophet (peace and blessings be upon him) there was a man speaking privately to him, so he (peace and blessings be upon him) seemed to be paying no attention to my father. We left him, and my father said: Did you not see your cousin, how he seemed to be ignoring me? I said: Father! There was a man with him speaking privately to him. He said: Was there someone with him? I said: Yes. So we went back, and he said: O Messenger of Allah! I said such and such to Abdullah, and he replied to me such and such; was there someone with you? He (peace and blessings be upon him) said: "Yes. O Abdullah! Did you see him?" I said: Yes. He (peace and blessings be upon him) said: "That was Jibril (peace be upon him); it was he who kept me occupied from you."
