Sahaabah did not ever differ in the 'aqeedah, the fundamentals, rather their differing was in the subsidiary affairs (furoo') of the Religion

Q: Is it permissible to say that the Companions differed on matters of `Aqidah (creed) such as the Prophet's (peace be upon him) seeing his Lord on the night of the Mi`raj (Ascension to Heaven) and the dead person hearing the living persons? Do such matters constitute part of the `Aqidah?

A: There was no difference or disagreement among the Companions or those following them from among Ahl-ul-Sunnah wal-Jama`ah (those adhering to the Sunnah and the Muslim main body) with regard to the Islamic `Aqidah. This is because they all believed in what is mentioned in the Qur'an and the Prophetic Sunnah. Moreover, they never introduced new practices into the religion. This was the reason for their unity and agreement on the same beliefs and the same method, acting upon Allah's Saying,"And hold fast, all of you together, to the Rope of All'ah (i.e. this Qur'an), and be not divided among yourselves."(Surah al-Imran 3:103)

One of these beliefs is the belief that the believers will see their Lord on the Day of Resurrection, as all agree on this belief as is proven by the reported proof from the Qur'an and the Prophetic Sunnah. They never differed on such belief.

As for the difference and disagreement on the question whether the Prophet (peace be upon him) saw his Lord on the night of the Mi`raj with his physical eyes or not, there is a disagreement on a particular event in this life, not a disagreement on seeing Allah (may He be Exalted) on the Day of Resurrection. The majority of scholars are of the opinion that the Prophet (peace be upon him) saw his Lord with his insight, not with his eyes. This is because when the Prophet (peace be upon him) was asked about this point, he said, "Light, how could I see Him." Thus, the Prophet (peace be upon him) negated seeing his Lord in this situation out of the light which prevented him from seeing his Lord. Also, scholars unanimously agree that no one can see his Lord in the life of this world, as mentioned in the Prophetic Hadith, where the Prophet (peace be upon him) said, "No one of you shall see his Lord until he dies." (Related by Muslim). It is worth mentioning that our Prophet Muhammad (peace be upon him) is excluded from this rule, as he saw his Lord, but not in this way.

May Allah grant us success! May peace and blessings be upon our Prophet Muhammad, his family and Companions!

As for the Sahaabah, then the Scholars, both past and present such as Ahmad Ibn Hanbal, Ibn Taymiyyah, Ibn Baaz and Al-Fawzaan, have mentioned the following important points:

1. ............

2. That though the Sahaabah differed, which may have led to fighting, this differing was never in the usool or the fundamentals of the Religion, such as the belief in the Attributes of Allaah, the belief in Qadr and the rest of the affairs of usool such as Imaamah (rulership) and rebellion. This has been stated by Ibn Taymiyyah and others (see Minhaajus-Sunnah of Ibn Taymiyyah). And the books of 'aqeedah repeat over and over this important fact. Shaikh Al-Fawzaan mentions in his explanation of Al-Barbahaaree's 'Sharhus-Sunnah' that the Sahaabah did not ever differ in the 'aqeedah, the fundamentals, rather their differing was in the subsidiary affairs (furoo') of the Religion.
