Silsilat al-Ahadith al-Sahihah

Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates that we were sitting with the Messenger of Allah (peace and blessings be upon him), and Sayyiduna Amr bin al-As (may Allah be pleased with him) had to go with me, so he went to put on his clothes. The Messenger of Allah (peace and blessings be upon him) said: "Now a cursed man will enter upon you. By Allah! I remained in anxiety and distress (wondering who would be deserving of this warning), and I kept watching those coming and going, until Hakam bin Abi al-As entered."
