Abd al-Rahman bin al-Zajjaj narrates: I asked Sayyiduna Shaybah bin Uthman (may Allah be pleased with him): "O Abu Uthman, people say that the Prophet (peace and blessings be upon him) entered the Ka'bah but did not pray in it." He replied: "They are wrong. The Prophet (peace and blessings be upon him) prayed two rak'ahs between the two pillars, and then pressed his stomach and his back against them."
Al-Tabarani recorded it in al-Mu'jam al-Kabir; its chain contains Abd al-Rahman bin al-Zajjaj, and I have not found anyone who has written his biography.
