Five beliefs are the fundamentals in Islam
But Bukhari and his five – three pillars not in the Qur’an
2:285 The Messenger has full conviction in what is revealed to him from his Lord and so do the believers. Each one of them believes in God, His angels, His Books and His Messengers. (They say), 'We make no distinction between any of His
Messengers.' And they say, 'We hear and we obey, so grant us the protection of forgiveness, our Lord. The final destination of all journeys is unto You.' [No distinction since all of them were sent by the same Creator and they were
one in purpose. 2:253, 17:55]
Five beliefs are of fundamentals in Islam. a) The oneness of Allah, b) His angels c)His Books d)Finality of the Prophethood in the person of Prophet Muhammad, [as]; and e) Accountability of the Day of Judgment.
But Bukhari and his five – three pillars not in the Qur’an, salah,fasting and zakat.
On the authority of Abdullah, the son of Umar ibn al-Khattab (ra), who said:
I heard the Messenger of Allah (ﷺ) say, "Islam has been built on five : testifying that there is no deity worthy of worship except Allah and that Muhammad[as] is the Messenger of Allah, establishing the salah , paying the zakat , making the hajj to the House, and fasting in Ramadhan." [Bukhari & Muslim]

My 2 cents
As I always said , Bukhari and his gang never existed.
The sectarian Ummah on a rough roller coaster ride for the last 1250 years. Courtesy fake narrations from, besides several locations , two main one BK[ not burger king]. Busra and Kufa , the residents as of today may speak Arabic but their DNA-Persian.
