Our Holy Prophet (PBUH) didnot openly nominate anyone as his succsssor. However Hazrat Abu Bakr had on occasions been nominated to lead the prayers and Hazart Ali was a preferred Army commander.
You forget that the Prophet said, Man Kuntu Mawla fi Haza Aliun Mawla, whosever master I am, Ali is his master.
Dr. Tahir ul Qadri (Allah protect him), one of the best scholars of our time, has written a book on this topic named after the event, Ghadir Khum, where he proves this saying using 50 Sahih Hadith and the conclusion that he comes to is that
Imam Ali (AS) is the spiritual successor of the Prophet. Something that all Sufis and Philosophers agree on.
Hadīth No. 9
عن زيد بن أرقم رضي الله عنه, قال: خرجنا مع رسول الله صلى الله عليه وآله وسلم حتى انتهينا إلى غدير خم, فأمر بروح فكسح في يوم ما أتى علينا يوم كان أشدّ حرًا منه, فحمد الله وأثنى عليه, وقال: يا أيها الناس! أنه لم يبعث نبي قط إلا ما عاش نصف ما عاش الذي كان قبله, وإني أوشك أن أدعى فأجيب, وإني تارك فيكم ما لن تضلوا بعده كتاب الله عز وجل. ثم قام فأخذ بيد علي رضي الله عنه, فقال: يا أيها الناس! من أولى بكم من أنفسكم؟ قالوا: الله ورسوله أعلم. ألست أولى بكم من أنفسكم؟ قالوا: بلى. قال: من كنت مولاه فعلي مولاه.
“Zayd bin Arqam (رضي الله عنه
narrates: We set out with Allāh’s Messenger (صلى الله عليه وآله وسلم
until we reached Ghadīr Khum. He commanded that a canopy should be put up. He looked tired on that day and it was a very hot day. He praised Allāh and then said: O people, out of the prophets Allāh sent, each new prophet had a life span half as much as that of his predecessor, and it seems to me that soon I may be called (to breathe my last) which I shall accept. I am leaving in your midst something that will never let you go astray, and that is the Book of Allāh . Then he stood up, held ‘Alī’s hand and said: O people, who is he who is nearer than your lives? All of them said: Allāh and His Messenger (صلى الله عليه وآله وسلم
know better. (Then added
Am I not nearer than your lives? They said: Why not! He said: One who has me as his master has ‘Alī as his master.”[9]
Hadīth No. 10
عن سعد بن أبي وقاص رضي الله عنه, قال: لقد سمعت رسول الله صلى الله عليه وآله وسلم يقول في علي رضي الله عنه ثلاث خصال, لأن يكون لي واحدة منهن أحب إلي من حمر النعم:
سمعته يقول: إنه بمنزلة هارون من موسى, إلا أنه لا نبي بعدي, وسمعته يقول: لأعطين الراية غدا رجلا يحب الله ورسوله, ويحبه الله ورسوله, وسمعته يقول: من كنت مولاه فعلي مولاه.
“Sa‘d bin Abī Waqās (رضي الله عنه
says that he heard Allāh’s Messenger (صلى الله عليه وآله وسلم
describe three qualities of ‘Alī (رضي الله عنه
. Had I possessed anyone of them, it would have been dearer to me than red camels.
“I heard him say: Indeed, he (‘Alī
is in my place as Hārūn was in Mūsā’s place, but there is no prophet after me. And I heard him say: Today I shall bestow the flag on the person who loves Allāh and His Messenger (صلى الله عليه وآله وسلم
, and Allāh and His Messenger (صلى الله عليه وآله وسلم
love him too. And I heard him say: One who has me as his master has ‘Alī as his master.”[10]
Harun was Musa's successor - the Prophet points out, your position to me is like Harun to Musa.
If there was just 1 hadith like this in regards to Abu Bakr, there would be NO DOUBT that he was the successor, however they WASNT any, and there are at least 50 sahih hadith about Imam Ali, yet people still dont accept.
From the Shia side Imam Jaafer Al Saadiq was considered as scholar equal to Imam Abu Hanifa. Fiqah and Sharia divide started at this point. Nearly all Shias including Ismailis accept Imam Jaafer's Fiqah.
Abu Hanifa, was Imam Jafer as Sadiq (AS)'s student. As was Imam Malik. At Al Azhar, all 5 fiqhs are taught.
Sunnis revere the Prophets companion and hold them in higher esteem than his family, saying that the right to rule comes from consensus. Although the first was elected by a few people (several prominent sahaba, ansar were missing from the meeting because they were concered with burying the Prophet SAWW), the second appointed by the first and the third elected by a committee of 6 whereas the entire ummah turned to Imam Ali to be caliph when the third died.
Shias revere what they believe to the righteous companions and hold the Prophets family in highest esteem, and claim the right to rule comes from Allah. We have a different account of the characteristics of the first three caliphs which we can prove using Sunni books, where we can cite inconsistencies and lack of islamic knowledge. But then again, that is not stripping them of any of their accomplishments we simply maintain they were not purified as the Ahlul Bayt were (Qur'an 33:33) and were not entitled to rule.

Shias follow 12 Infallible Imams after the Prophet with the last being Imam Mahdi, who we await and belive is alive. Prophet said he would be of my progeny, this strenghtens the case for his progeny to succeed him.
All Sufi orders trace their spiritual knowledge back to Imam Ali via most of the Shia imams, Qadriyyah trace it from our 8th Imam back through 7 Imams to Imam Ali, others via Jafar as Sadiq etc. Naqshbandi are supposed to derive from Abu Bakr, however their chain includes Jafar as Sadiq.
All of our Imams were killed by the caliphs of the time, and Shias were always persecuted.
In the Absense of the Imam, Shias in terms of spiritual and worldy matters refer to who they believe to be the most learned. The most knowledgeable scholars are called Marjas, and they have the title of Ayatullah.
We were all knowns as Shias, You were either Shia of Ali, or Shia of Uthman in history books. So the split didn't come after them, it was always there as is noted by authors like ibn Kathir who referred to us as Shia of Uthman or Ali.
Shias and Sunnis differ in that Sunni scholars of hadith mainly took hadith from companions and companions of companions whereas Shia scholars of hadith relied on Ahlul Bayt as their prime source.
Sunni books include Sahih Bukhari and Muslims,
Shia books include Al Kafi and Bihar al Anwar.
When Kufiites came down to Medina and martyred Hazrat Osman, most of the Omayyads never accepted Hazrat Ali as Khalifa. Battle of Siffin between Hazrat Ali and Muwayya was the main dividing factor. Muslims siding with Hazarat Ali came to be Known as Shi-aan e Ali or the group of Ali.
muawiyah (lanatullah) waged jihad against the Righteous Caliph Amir ul Momineen Ali ibn Abu Talib, and he was the first one to coin the phrase Ahle sunnah wal jamah. He was also responsible for killing Muhammed bin Abu Bakr.
