Sahaabah

The Khulafaa-e-Raashideen

Q: I have heard that Hazrat Mu'aawiyah (Radhiyallahu Anhu) is the fifth khalifa. I thought there are only four khalifas viz. Hazrat Abu Bakr, Hazrat Umar, Hazrat Uthmaan and Hazrat Ali (Radhiyallahu Anhum). Can you please give me the correct answer and was Hazrat Mu'aawiyah's (Radhiyallahu Anhu) status similar to the status of the four khalifas?

Did Hazrat Umar (Radiyallahu Anhu) divorce his wives because they were unable to conceive?

Q: Did Hazrat Umar (Radiyallahu Anhu) really divorced his two wives for the reason they were unable to conceive. If yes, how can an act of a person who is so respectable in the religion - considering he did have his kids from other wives and there were great Prophets in the history who had wives unable to have children yet they weren't respected, rather they were kept as wives and their statuses were honored forever.

Misleading comments regarding Hazrat Usmaan (Radiyallahu Anhu)

Q: I have questions about the Sahaba. 

1) Hazrat Abu Bakr has the highest status, followed by Hazrat Umar ibn Khattab. Who has the third position? Hazrat Usmaan or Hazrat Ali?

2)After the Khulafa-e-Rashideen, are the remaining six Ashra Mubashra the highest in status compared to the rest of Sahaba?

3) Some people, Nauzubillah, accuse Hazrat Usman bin Affaan of avoiding battles such as the Battle of Uhud, and accuse him of being a coward. Can you explain this matter please?
