Marhab's mother was a fortune-teller, she predicted that no man can kill Marhab but one man named after a synonymous of lion(Haider). A night before his last battle he saw in his dream that a lion attacked him.

Historians have given different descriptions about the incident of killing Marhab. According Sahih Muslim, Ali went to meet Marhab in a single combat. Marhab advanced brandishing his sword and chanting: "Khaibar knows certainly that I am Marhab, a fully armed and well-tried valorous warrior (hero) when war comes spreading its flames". Ali chanted in reply: I am the one whose mother named him Haidar, (synonymous of lion) like a lion of the forest with a terror-striking countenance". The narrator said: Ali struck at the head of Marhab and killed him, so the victory (capture of Khaibar) was due to him. Al-Maqrizi recorded: "The Ansari reported that he saw Marhab's mother holding his dead body and weeping".  According the Book History of Islam Vol-1 When Mola Ali a.s(First Imam of Muslim Ummah) hit Marhab bin Al Harith on the Head, the strike was as strong as it cut the body of Marhab in two equal pieces.
