Since Umar...
Since Umar, without any consultation, nominated Abu Bakr and then took oath of allegiance. Later on, Abu Bakr, without any consultation, handed over the reigns of Caliphate to Umar. However, (for the third caliph) Umar formed a Shura of six people, in which he did not include anyone from the Ansars [26] but only selected six people from the tribe of Quraish and excluded all others. He (Umar) drafted a will about them (six people) which neither you nor your accomplice will approve.
Ummro: What did Umar do? Imam -asws : Suhaab was asked to lead people in Salat for three days in a row. All of them (Muslims) should gather and offer Salat (behind him), excluding these six people along with a seventh-one, the son of Umar. There should not be anyone with them and the seventh-one should stay (in their company) but without giving any advice or involving in consultation.
Umar then told all those present among the Immigrants and Ansars, if they (six of them) are unable to reach a consensus after three days, you should kill all six of them. If after three days, four of them are in agreement but two of them are not then remove the heads of those two. Imam -asws : O Ummro! Would you and your companions agree to form a Shura, the way Umar formed to select a Ruler for Muslims? They all replied: No we are not in favour (of Shura)!
Imam -asws : O Ummro, let’s leave it (you will not form Shura as per your earlier intentions). Now, let us suppose, you succeeded in selecting a ruler for Muslims and everyone agreed on this selection, not even two people disagreed among the whole Muslim nation. You went to non-believers, who neither accepted Islam nor agreed to offer Jazia [27] .
In this case, do you or your selected ruler and Amir has the knowledge how Prophet Mohammed -saww implemented Jazia on the non-believers so that your actions are in accordance with the traditions of the Prophet -saww ? Ummro and others: Yes, we do. Imam -asws : How would you do decide? Ummro and others: We will first invite them to Islam but if they reject our invitation, we will force them to pay Jazia Imam -asws : What if they were people of the Book or are from fire worshippers?
Ummro: Yes, regardless if they were the people of Book or the fire worshippers. Imam -asws : What will you tell them if they were from those who worship fire and animals (Majusi)? Ummro! They are all equal. Imam -asws : Have you read sometime about them in the Holy Book? O Ummro: Yes, I have.
