Picking up on Ms. Ellen G. White, my micro-treatise on her foundational work in establishing the Seven-Day Adventist Faith, the physical demonstrations with and mystical implications that characterized her long visionary spiritual experiences shouldn't marvel anyone as being even uncommon. Excerpts physical experiences in vision, from the vault, which were are told is a secure, fireproof repository her original diaries, letters, manuscripts, and other documents, referred to as Lesser Light indicates that they were marked by lack of consciousness, lack of breathing, as she transcended the heavens, while holding an 8.4 KGs family bible, referred to as the Great Light and would encounter Angels receive messages. The outcome is heretical doctrine that denies righteousness and assurance of eternal life by faith in Christ Jesus. The exegesis for evidence of Ms. Ellen G. White as prophetic or rather as preferred, Messager or "frail instrument", is purely based on these physical demonstrations of mystical experiences, and revelations from whom she referred to as "my Instructor" or "the angel," while noting that she never ever claimed to have encountered Jesus or anything from him. 

The outcome of Madam Ellen White physical experiences and revealed messages from the angel, is sole foundation of the doctrine the Seven-Day Adventist, which  reconciles people to God through accepting 'The Sabbath', with the promise that those who accept and practice The Sabbath shall enter heaven, BUT, through progressive judgement based on works. Ms Ellen G White is thus, the Standard Model of Morality and Righteousness and the Foundation of the Seventh-Day Adventist. To a Seventh-Day Adventist means, you have to believe and be established in the message (Lesser Light) from the Messager, accept The Sabbath, and receive eternal life by works, and enter heaven through progressive judgements.  

Islamic Perspective: It should surprise you that the Islam Faith is modelled in very similar manner, like the Seventh-Day Adventist Faith, howbeit without the Islam morality dilemma of Mr. Mohammad PBUH. In like manner, Mr. Md had similar the physical demonstrations with and mystical implications that characterized her long visionary spiritual experiences.

In summary, at the 40 years, Mr. Md would trek from his residence with Khadija, about 3 km from Mecca to a cave in Hira on Mount al-Nour (or Noor which means Light), away from the idol worship and social evils of the Meccanites, for solitary retreats to reflect and worship on a God he hadn't yet discovered. The one night, an Angel, that Gabriel, appeared to him took him through a molesting and tormenting experience, that left him with  twitching neck muscles, his heart beating severely, terror shaken and trembling, and tormented with suicidal thoughts, and his wife would cover him and comfort him until fear would be over. The Angel tightly and rigorously pressed Mr. Md three times, forcing him to read, even as he kept crying out that he could read. Then the Angel revealed, by commanding him to recite words, though they had false excepts, became the first verse of the Quran. He citation claimed that God created man  from clot (blood clot). The wife Khadija would then, take him to her paternal cousin, Mr. Waraqa, who was by then old, and an Arab Christian convert and write of Gospels in Arabic, to enquire of what Mr. Md was going through. Its was Mr, Waraqa who, after the narration by Mr. Md, indicated it was Namus, that is Gabriel, who keeps the secrets, and who also whom Allah had sent to Moses. Mr. Waraqa also predicted the persecution of Mr. Md, but after a few days. _While Mr. Waraqa mentioned the Angel appearing to Moses, we it was the LORD who was in the burning but never consuming bush. (Sahih al-Bukhari 6982)

Thereafter, Mr. Md would be miraculously and lightening-fast, in single night,  be moved by white winged beast, from Mecca to and enter into Al-Aqsa Mosque in Jerusalem, leading other prophets in prayers😵‍💫. Then, he met with Gabriel, who would assist him to ascend to seven heavens to the divine presence of heaven and hell, while meeting various prophets at each, including Adam, Jesus, Joseph, Idris, Aaron, Moses, and Abraham🤔; had vision of afterlife; and bounced up and down negotiating the number Muslims need to pray in day, from the original 50 to 5 times (Surah Al-Isra 17:1).

The outcome of Mr. Md physical experiences, Angelic encounter, revealed messages from the angel, and ascension to the heavens, is sole foundation of the doctrine the Islam, which  reconciles people to God through confession of the 'Shahada' the first pillar of Islam Faith, with the promise that those who accept and practice The Five Pillars .Those with heavy sins (as measured the the 2 Angel, each siting on the shoulder of every Muslim), will be rescued from into hell fire at the ransom of Christian and Jew (Sahih Muslim (2767b, 432). Note the progressive salvation of Muslim by through the 5 Pillars, based on works, and additional opportunity ransom of Jew or Christian. Mr. Md is thus, the Standard Model Morality and Foundation of the Islam Faith.
