The sahaba:
1. Qumi in his tafsir, “Tafsir Qumi” narrates from Abi Abdullah:
“When the prophet (sws) was in the cave, he (sws) said to Abu Bakr (ra), “I see the ship of jaffar in the river with his companions. And likewise i see the ansar. Abubakr (ra) asked can i also see? The prophet (sws) said , “yes”. Abubakr asked how? The prophet did masah with his hands on abubakr’s eyes. Thus, abubakr saw what the prophet saw. Then, the prophet turned to abubakr and said, “You are siddique.”
Tafsir Qummi, 1/289
Again maybe the brothers know the grading?
Sahifa e Sajjadiya of Ali Zayn Al Abideen ibn Hussain ibn Ali ibn Abu Talib, Dua 4: Blessings upon the attesters to the Messengers:
O Allah, and as for the Companions of Muhammad specifically, those who did well in companionship, who stood the good test in helping him, responded to him when he made them hear his messages' argument, separated from mates and children in manifesting his word, fought against fathers and sons in strengthening his prophecy, and through him gained victory; those who were wrapped in affection for him, hoping for a commerce that comes not to naught in love for him; those who were left by their clans when they clung to his handhold and denied by their kinsfolk when they rested in the shadow of his kinship; forget not,
O Allah, what they abandoned for Thee and in Thee, and make them pleased with Thy good pleasure for the sake of the creatures they drove to Thee while they were with Thy Messenger, summoners to Thee for Thee. Show gratitude to them for leaving the abodes of their people for Thy sake and going out from a plentiful livelihood to a narrow one, and [show gratitude to] those of them who became objects of wrongdoing and whom Thou multiplied in exalting Thy religion.
O Allah, and give to those who have done well in following the Companions, who say, Our Lord, forgive us and our brothers who went before us in faith, Thy best reward; those who went straight to the Companions' road, sought out their course, and proceeded in their manner. No doubt concerning their sure insight diverted them and no uncertainty shook them from following in their tracks and being led by the guidance of their light. As their assistants and supporters, they professed their religion, gained guidance through their guidance, came to agreement with them, and never accused them in what they passed on to them.
O Allah, and bless the Followers, from this day of ours to the Day of Doom, their wives, their offspring, and those among them who obey Thee, with a blessing through which Thou wilt preserve them from disobeying Thee, make room for them in the plots of Thy Garden, defend them from the trickery of Satan, help them in the piety in which they seek help from Thee, protect them from sudden events that come by night and day - except the events which come with good - and incite them to tie firmly the knot of good hope in Thee, what is with Thee, and refrain from ill thoughts [toward Thee] because of what the hands of Thy servants' hold.
Nahjul Balagha, vol.3, p.648, sharif al radi:
"In the beginning of our matter, the people of Sham and us met. It is obvious that our God is one, our Prophet is one, and our call in Islam is one. We do not see ourselves more in faith in Allah or more in believing His messenger than them, nor they do. Our matter is one, except for our disagreement in Uthman’s blood, and we are innocent from his murder."
