As-salaamu `alaykum.
Jazaak Allaahu khayran for the beneficial reminder. The third man could have been `Ikrimah Ibn Abee Jahl, may Allaah be pleased with him. He was shaheed not long after entering Islaam, and the same event was reported about his death.
May Allaah be pleased with all of the companions, and destroy those who dare defame them.
Was-salaam
