When nothing could be put in writing...
When nothing could be put in writing, there was no other way except to make guesses. If the guess of Ahlul Sunnat is correct, Umar did very much against not only Abu Bakr but also against the entire Ummah, because, had Abu Bakr been appointed as the Caliph in writing, no Muslim could have ever disputed it and there would not have been any tussle about Caliphate in the Muslim world and all the Muslims would have followed one and the same way.
Shias say that the Prophet intended to appoint Ali (a.s.) as his successor in writing and it was so because, only a few months earlier, the Holy Prophet (S) had orally made Ali (a.s.) his successor at a place called Ghadeer Khumm.[^3] The author intends to give details of Ghadeer Khumm in the following pages, which will show that the claim of Shias does not appear baseless. Anyway, whatever the fact may be, it does not appear that Umar did anything against the Caliphate of Abu Bakr.
If Umar was certain that the Prophet was about to make Abu Bakr his Caliph in writing, he would have, instead of preventing the Prophet from such a writing, all the more tried for the conclusion of such a written document, because such writing would surely have resulted in what had happened at the gathering of Saqifah Bani Saada with the support of Umar. But as a matter of fact, Umar too was certain that the Prophet wanted to make Ali his successor in writing.
Ahmad bin Abi Tahir has, in Tarikh Baghdad, quoted a narration of Ibn Abbas that Umar himself had said that the Prophet wanted to mention the name of Ali clearly during his last illness, but that “I prevented it.” That is why he objected. It will be seen henceforth that Umar had always tried to keep His Eminence, Ali (a.s.) away from Caliphate.
All know that Umar kept Ali away from Caliphate during his (Umar’s) lifetime very successfully and even after his death, Umar, with his unparalleled political diplomacy, did not allow Ali to succeed as a Caliph. There is no doubt that non-realization of the Prophet’s intention was a great misfortune for the Muslim Ummah, sorrow for Islam and followers of Islam.
“Surely we belong to Allah and to Him we shall return.” [^4] Had that writing come into effect, Islam would have remained safe from thousands of mischief-makers and would not have suffered any of the calamities, which it is facing?
