I believe that Rev. 11:15 refers to Baha’u’llah, who was the seventh angel:
“The seventh angel is a man qualified with heavenly attributes, who will arise with heavenly qualities and character. Voices will be raised, so that the appearance of the Divine Manifestation will be proclaimed and diffused. In the day of the manifestation of the Lord of Hosts, and at the epoch of the divine cycle of the Omnipotent which is promised and mentioned in all the books and writings of the Prophets—in that day of God, the Spiritual and Divine Kingdom will be established, and the world will be renewed; a new spirit will be breathed into the body of creation; the season of the divine spring will come; the clouds of mercy will rain; the sun of reality will shine; the life-giving breeze will blow; the world of humanity will wear a new garment; the surface of the earth will be a sublime paradise; mankind will be educated; wars, disputes, quarrels and malignity will disappear; and truthfulness, righteousness, peace and the worship of God will appear; union, love and brotherhood will surround the world; and God will rule for evermore—meaning that the Spiritual and Everlasting Kingdom will be established. Such is the day of God. For all the days which have come and gone were the days of Abraham, Moses and Christ, or of the other Prophets; but this day is the day of God, for the Sun of Reality will arise in it with the utmost warmth and splendor.”

Revelation 10:1 Then I saw another mighty angel coming down from heaven. He was robed in a cloud, with a rainbow above his head; his face was like the sun, and his legs were like fiery pillars.
And yet another angel. Who is this one? This is during The Bab's 2nd Woe. But other stuff happens during the 2nd Woe.
Chapter 11:1 ...“Go and measure the temple of God and the altar, with its worshipers.
2 But exclude the outer court; do not measure it, because it has been given to the Gentiles. They will trample on the holy city for 42 months.
3 And I will appoint my two witnesses, and they will prophesy for 1,260 days, clothed in sackcloth.”
7 Now when they have finished their testimony, the beast that comes up from the Abyss will attack them, and overpower and kill them.
8 Their bodies will lie in the public square of the great city...
9 For three and a half days...
11 But after the three and a half days the breath of life from God entered them, and they stood on their feet, and terror struck those who saw them.
12 Then they heard a loud voice from heaven saying to them, “Come up here.” And they went up to heaven in a cloud, while their enemies looked on.
13 At that very hour there was a severe earthquake and a tenth of the city collapsed. Seven thousand people were killed in the earthquake, and the survivors were terrified and gave glory to the God of heaven.
14 The second woe has passed; the third woe is coming soon.
So... the 2nd Woe is supposedly The Bab, but what are these 2 Witnesses doing here? Baha'is say that the 2 Witnesses are Muhammad and Ali. They've been and gone. Or, the is not about The Bab. Which is it? And then this mysterious earthquake. Baha'is say an earth happened right after The Bab was killed. Is there proof of it happening? And, did a tenth of the city collapse and did 7000 people die? And so ends the 2nd Woe. And now the 3rd Woe and the 7th Angel.
Rev 12:1 A great sign appeared in heaven: a woman clothed with the sun, with the moon under her feet and a crown of twelve stars on her head.
2 She was pregnant and cried out in pain as she was about to give birth.
3 Then another sign appeared in heaven: an enormous red dragon with seven heads and ten horns and seven crowns on its heads.
4 Its tail swept a third of the stars out of the sky and flung them to the earth. The dragon stood in front of the woman who was about to give birth, so that it might devour her child the moment he was born.
5 She gave birth to a son, a male child, who “will rule all the nations with an iron scepter.” And her child was snatched up to God and to his throne.
6 The woman fled into the wilderness to a place prepared for her by God, where she might be taken care of for 1,260 days.
What? This is Baha'u'llah's Woe. Why are we going back to some more references to 1260 days that get converted to years that get converted to lunar years that show that the time from the Hegira to the declaration of The Bab is year 1260 in the Islamic calendar? We are done with that. Now we need some indication that this 3nd Woe is Baha'u'llah. And that this Angel is him also. What do we have? We have beasts and dragons.
Rev 13:1 The dragon stood on the shore of the sea. And I saw a beast coming out of the sea. It had ten horns and seven heads, with ten crowns on its horns, and on each head a blasphemous name.
2 The beast I saw resembled a leopard, but had feet like those of a bear and a mouth like that of a lion. The dragon gave the beast his power and his throne and great authority.
3 One of the heads of the beast seemed to have had a fatal wound, but the fatal wound had been healed...
5 The beast was given a mouth to utter proud words and blasphemies and to exercise its authority for forty-two months.
11 Then I saw a second beast, coming out of the earth. It had two horns like a lamb, but it spoke like a dragon.
12 It exercised all the authority of the first beast on its behalf, and made the earth and its inhabitants worship the first beast, whose fatal wound had been healed...
The second beast was given power to give breath to the image of the first beast, so that the image could speak and cause all who refused to worship the image to be killed.
16 It also forced all people, great and small, rich and poor, free and slave, to receive a mark on their right hands or on their foreheads,
17 so that they could not buy or sell unless they had the mark, which is the name of the beast or the number of its name.
18 This calls for wisdom. Let the person who has insight calculate the number of the beast, for it is the number of a man. That number is 666.
And what does this have to do with Baha'u'llah? Baha'is have told me these beasts and dragons are the Umayyads and Abbasids. We are going back to the time of the 1st Woe? Anyway, next comes some interesting stuff.
Rev 14:1 Then I looked, and there before me was the Lamb, standing on Mount Zion, and with him 144,000 who had his name and his Father’s name written on their foreheads.
6 Then I saw another angel flying in midair, and he had the eternal gospel to proclaim to those who live on the earth—to every nation, tribe, language and people.
7 He said in a loud voice, “Fear God and give him glory, because the hour of his judgment has come. Worship him who made the heavens, the earth, the sea and the springs of water.”
8 A second angel followed and said, “ ‘Fallen! Fallen is Babylon the Great,’ which made all the nations drink the maddening wine of her adulteries.”
9 A third angel followed them and said in a loud voice: “If anyone worships the beast and its image and receives its mark on their forehead or on their hand,
10 they, too, will drink the wine of God’s fury..
The Lamb? Who's the Lamb? The 7th Angel/3rd Woe who Baha'is say is Baha'u'llah has already come. Now what? Are you going to say Baha'u'llah is the Lamb also? But who are these 144,000? They are the ones that sing the new song. But we've got more angels. Are they manifestations too? But the 3rd angel is still talking about the mark of the beast. But what about this mark or number of the beast... the 666? One Baha'i said that it is the year that the Umayyads took control of Islam. How again does that work? I mean in context. I know how he made it work. I believe 661 was the year he needed so he added 5 years to that to get to 666. He got the 5 years because Jesus was born approximately 5 years before year zero. But, whatever.
Rev 15:1 I saw in heaven another great and marvelous sign: seven angels with the seven last plagues—last, because with them God’s wrath is completed.
Now what? 7 more angels? But the 7th one out of the last group of angels was Baha'u'llah? And, it is with this one the wrath of God is completed? Hmmm? Plagues and disasters follow... ugly stuff then...
Rev 18:10 “ ‘Woe! Woe to you, great city, you mighty city of Babylon! In one hour your doom has come!’
16 ...“ ‘Woe! Woe to you, great city...
17 In one hour such great wealth has been brought to ruin!’
More "Woes"? I thought Baha'is said "Woes" are manifestations? I guess not, huh?
Rev 19:7 Let us rejoice and be glad and give him glory! For the wedding of the Lamb has come, and his bride has made herself ready.
8 Fine linen, bright and clean, was given her to wear.” (Fine linen stands for the righteous acts of God’s holy people.)
9 Then the angel said to me, “Write this: Blessed are those who are invited to the wedding supper of the Lamb!” And he added, “These are the true words of God.”
10 At this I fell at his feet to worship him. But he said to me, “Don’t do that! I am a fellow servant with you and with your brothers and sisters who hold to the testimony of Jesus. Worship God! For it is the Spirit of prophecy who bears testimony to Jesus.”
11 I saw heaven standing open and there before me was a white horse, whose rider is called Faithful and True. With justice he judges and wages war...
19 Then I saw the beast and the kings of the earth and their armies gathered together to wage war against the rider on the horse and his army.
20 But the beast was captured, and with it the false prophet who had performed the signs on its behalf. With these signs he had deluded those who had received the mark of the beast and worshiped its image. The two of them were thrown alive into the fiery lake of burning sulfur.
We're not even at the end of Revelation yet. But here we've got this Lamb again. Jesus is mentioned by name. And the beast is finally captured and thrown into a fiery pit. This beast that the Baha'is say was either the Umayyads or Abbasids or both. If ever Revelation would be talking about Baha'u'llah, it would be now and to the end of Revelation. Are you sure you have all this interpreted correctly? Are you sure Baha'u'llah has fulfilled all the prophesies? Of course you are. Let me end with the final words of Revelation again...
Rev 22:16 “I, Jesus, have sent my angel to give you this testimony for the churches. I am the Root and the Offspring of David, and the bright Morning Star.”
20 He who testifies to these things says, “Yes, I am coming soon.”Amen. Come, Lord Jesus.
21 The grace of the Lord Jesus be with God’s people. Amen.
Why does it say "I, Jesus"? Why does it say "Come, Lord Jesus"? I cannot blame Christians one bit for believing it is Jesus coming back. And, I cannot blame them for not believing that Baha'u'llah is the return of Christ.
