When prophet Muhammad was supported by God (Allah) with His miracle of going from Mecca to Al-Quds (Jersalem) and then ascending to the Heavens in one night, the unbelievers rushed to Abu Bakr and told him what they heard from the prophet. Then, Abu Bakr told them if the prophet said so then it is true. If we believe him in what revealed to him by God from the Heavens through the Angel Gabriel (Jibril) then we should believe in all what he says. Then the prophet titled him as Al-Sadique which is an Arabic word that means the absolute truthful.
Caliphs

Hazrat Zaid bin Sabit was given the title of "Scribe of the Prophet" due to his role in recording and preserving the revelations of the Quran during the time of Prophet Muhammad.
It depends on the prophet in question.
prophet, also Hazrat is a title meaning Mr. or Sir.
Caliph
Caliph (or Khalifa in Arabic)
ayshaAnswer 2The first wife of prophet SAWW Khadijah and the daughter of prophet Hazrat Fatima Zahra a.s. have the title Tahira (purified). also there are many fabricated hadith about Aisha.
The third Caliph Uthman Ibn Affan.
Imam because Quran says prophet Ibrahim a.s. could reach to this rank after passing exams. so Imam is a higher rank than prophet. also Messenger of God Muhammad SAWW was both messenger and Imam at the same time. Imam has two meanig: one is a general word used by people about any leader so in this meaning it is given as a title by people. but another meaning is specific and is a title given by God to special people who are infallible and are representative of God and are leader of humans for religion and meeting God. word of Imam is used in Quran in different verses. for example God gives the title of Imam to prophet Ibrahim a.s. in below verse and so Imam is given to some leaders. according to Shia Islam Messenger Muhammad SAWW was an Imam and after him God selected 12 Imams and 12th of them is currently alive but at occultation and still some beleivers can meet him. the verse that says God given title of Imam to prophet Ibrahim a.s. after passing exams is this: And remember that Abraham was tried by his Lord with certain commands, which he fulfilled: He said: "I will make thee an Imam to the Nations." He pleaded: "And also (Imams) from my offspring!" He answered: "But My Promise is not within the reach of evil-doers." [2:124] Any prophet/messenger is not Imam and any Imam is not prophet/messenger. for each one there are requirements that after tries one can have it. there are prophet in history who were not Imam and there are Imams in history who are not prophet. _____________________________________________________- Imam or Alimam AlAkbar (Sheikh Algamea AlAzhar). However the title Imam or Alimamam AlAkbar are titled given by people but prophet and/or messenger are titles given by Allah (or God in English and same God in Christianity and Judaism). So, it is logic that prophet/messenger is of higher rank than Imam/AlImam. Any prophet/messenger is Imam to his people but not every Imam is prophet/messenger.
The successors to the Prophet Muhammad were called the Caliphs. Muhammad's father-in-law, Abu Bakr, was elected as the first Caliph. Then came Umar and Uthman. The fourth Caliph was Ali ibn Abi Talib, the cousin and son-in-law to Muhammad, whom the Shi'ites believe to have nominated Ali to be his immediate successor. Disagreement over the succession became a major cause of friction and led to the division of Islam along Sunni and Shia lines.
The highest leader of Islam is prophet Muhammad (PBUH).
