According to the majority of the Muslims, it is justified. The Shias don't think so.
he was dedicated and Muhammad liked that about him when Muhammad was alive.Answer B (shia view)he claimed Abubakr left a will letter and appointed him as Caliph. but there are some references saying Uthman himself wrote that letter and when Abubakr died Uthman used his stamp to attribute that letter to Abubakr. Anyway he was not selected by God or prophet or people or any meeting or shura. and he was selected by Abubakr.
Muawiyah made the office of Caliph hereditary.
After the death of the Prophet (SAW), Hazrat Abu Bakr Siddique (RAU) was chosen the Muslim Ruler. His title was 'The Caliph of the Rasool'. All the subsequent Caliphs were called Ameer-ul-Momineen. The title is generally called 'Caliph'.
Caliph meaning the representative of God on earth
maybe caliph?
No, that title is "Caliph", not Czar.
The title of the Islamic Empire was Caliphate. The Caliph was called Amir-ul-Momineen.
Caliph
This depends on what you mean by the word caliph. If you are referring to the rightfully guided Caliphs, who came right after the death of the Prophet Muhammad (S), then the last one, Hasan ibn Ali (RA) died in the year 50 After Hijra. There is debate about whether he or Ali ibn Abi Talib, his father, is the last of the rightfully guided Khalifas. Ali died in 40 AH. The Caliphate, however, was never officially abolished until the year 1924 AD, or 1343 AH. The last Caliph, Abdulmecid the second of the Ottoman Empire, was forced to abolish his title upon the formation of the Republic of Turkey.
No. The title taken by Muslim rulers who assert religious authority is typically Caliph or Ayatollah. The Czar was a term used to designate the Russian Kings.
