For a perfect election...
For a perfect election, it was necessary that all the chiefs of all the areas must be gathered. But this did not happen. In this haste, leave alone the people of Hijaz, even all the respectable personalities of Medina could not be summoned. The people of decision will themselves decide to what extent is correct the claim of Ahlul Sunnat that Abu Bakr became the Caliph by consensus. Indeed, this weak claim of the supporters of consensus is defective was well known to even those people.
But for the need of religion they consider it rightful. The believers of consensus have also believed that consensus is correct even if two people other than Bani Hashim take part in it. On the other hand, if thousands of Bani Hashim effect a consensus, it shall not be accepted as valid. Obviously, these types of bigotries create many disconcerting views in the minds of unbiased and just people. There is no need to mention them.
Those who claim it was an election, must see it with absolute sincerity was it really a fair election that was effected in a hurried manner at Saqifah Bani Saada? Though we confess to the cunning of Umar, who easily wrested Caliphate from Bani Hashim so easily that they could not do anything. Though Bani Hashim were once considered indispensable for Caliphate.
If he had desired, Umar could have passed on the benefit of this consensus to Ali (a.s.) but he did not like Ali (a.s.) due to a number of factors. That is why in the absence of Ali (a.s.), he made Abu Bakr the Caliph. Although Umar and Ali (a.s.) had such opposite traits that friendship between them is unimaginable, but apparently it seems that Umar had extreme hatred towards Fatima (s.a.). Thus, he could not bear any good for Ali (a.s.).
The cause of this enmity seems that Umar had once desired to marry the Lady of Paradise, but the Holy Prophet (S) on the basis of his hidden wisdom, married her to Ali (a.s.). Umar very well knew that Abu Bakr had no merit in comparison to Ali (a.s.), but he pledged allegiance to him and other people at Saqifah were also compelled to do the same. The other people did not hesitate in giving allegiance to Abu Bakr. They did not even ask why any member of Bani Hashim was not present.
Without considering if Abu Bakr had any superiority to Ali (a.s.), they followed Umar in giving allegiance. This definitely did not prove beneficial to Islam.
