The Book of Revelation alludes to a “little book” which would be sent down by an angel to mankind. The little book is in Revelation 10, uses the greek word translated “bible” by Herbert W Armstrong, Strong’s number 974) similar to the word in Revelation 20:12, Strong’s number 975. God has warned us ahead of time that another little book of revelation was coming!
This means a later edition of “Scripture” is to be revealed, by the seventh angel (Revelation 10:7). Perhaps this is an angel presiding in the “seventh” heaven rather than being a seventh angel.
Revelation 10:1-2, “I saw still another mighty angel coming down heaven, clothed with a cloud. And a rainbow was on his head, his face was like the sun, and is feet like pillars of fire. He had a little book [BIBLE,SCRIPTURE], open in his hand. And he set his right foot on the sea and his left foot on the land and cried with a loud voice, as when a lion roars. When he cried out, seven thunders uttered their voices.”
The Little Book is associated with the number 7. It is the seventh angel (or angel residing in the 7th heaven) revealing the book, uttering 7 thunders. The thunders is the message contained inside the little book. This book is associated with scripture (Rev 10:2; 20:12). If all scripture had already been revealed there would be no need for another revelation to come down by an angel.
In the article: Number 7 in the Quran:
The number of heavens is seven, and when we look in the Quran for the statement “seven heavens” we find that it is repeated seven times throughout the whole Quran exactly as the number of heavens!
Among all the numbers, the number 7 is the first number stated in the Quran.
When we look for the appearing frequencies of all the numbers in the Quran, we find that the number 7 is the most repeated number after the number 1.
When we look at the first chapter in Allah’s book, that is Al-Fatihah (the opening), we find that it is made of seven verses, and it is composed of twenty-one alphabets, which is a multiple of 7 (21=7×3).
But the astonishing thing in this great Sura which consists of 7 verses is that the number of letters of Allah’s name in this Sura is seven times seven!!! i.e. the number of the letters “A”, “L” and “H” in this Sura is 49 letters, i.e. 7×7.
God Almighty has told us about the number of the doors of Hell, may Allah protect us from it, when He said: “To it are seven Gates.” (Al-Hijr 15:44).
We find that the word “Hell” is repeated 77 times throughout the whole Quran and this number is also a multiple of 7, and made of 7 and 7, and equal to 7×11, so, Hell has seven gates and was repeated in the Quran in a number of times that is a multiple of seven.
In the Masonic book: The Entered Apprentice by JSM Ward (of the number 7):
The Ancient Egyptians held this view , and it is endorsed in Masonry by the fact that it takes seven to make a perfect lodge. There is also, no doubt, an astrological reference to the seven planets and a connection with stellar worship, but as our system is mainly solar, it is almost impossible to give a logical planetary interpretation to the seven who form a lodge, or to the seven officers. In short, the planetary symbolism has become disorganized by the stress laid on the solar aspect of the three principal officers who rule a lodge. Moreover, the predominance of the solar aspect has emphasized the triune nature of man, and symbolizes it in these officers.
7 in the Bible has many references so it wouldn't be a surprise for the Quran to have similar links. It is a number of "completion". For a thoroughly breakdown of 7 in the Bible go to Biblestudy.org.
See also The Bible Wheel on the number 7:
In Scripture, seven symbolizes completeness or perfection. On the seventh day God rested from his labors and creation is finished (Gn 2:2). Pharaoh in his dream saw seven cattle coming from the Nile (41:2). Samson’s sacred Nazirite locks were braided in seven plaits (Jgs 16:13). Seven devils left Mary of Magdala, signifying the totality of her previous possession by Satan (Lk 8:2); "seven other devils" will enter the purified but vacant life of a person (Mt 12:45). However, on the positive side, there were the seven spirits of God (Rv 3:1). In the seventh year the Hebrew slave was to be freed (Ex 21:2), having completed his time of captivity and service. Every seventh year was a sabbatical year (Lv 25:4). Seven times seven reiterates the sense of completeness. In the Year of Jubilee (at the completion of 7 x 7 years = the 50th year), all land is freed and returns to the original owners (Lv 25:10). Pentecost, the Feast of Weeks, is seven times seven days after Passover. "Seventy," which is literally "sevens" in Hebrew, strengthens the concept of perfection. There are 70 elders (Ex 24:1) in Israel. Israel was exiled to Babylon for 70 years (Jer 25:12) to complete its punishment. "Seventy times seven" (Mt 18:22) reiterates this still further. The Lord was not giving Peter a mathematical number of times that he should forgive another person, but rather was insisting on limitless forgiveness for a brother’s sin.
The Interlinear Bible translates Revelation 10:7, “but in the days of the voice of the seventh angel, whenever he is about to trumpet, was even ended the mystery of God, as He preached to His slaves, the Prophets.” The Quran is full of references of God’s followers being “slaves” of God in the Noble edition. Surah 66:10, “God sets forth an example for those who disbelieve: the wife of Noah and the wife of Lot. They were under two of our righteous slaves, but they both betrayed them (their husbands by rejecting their doctrine). So they (Noah and Lot) availed them (their respective wives) not against God and it was said, “Enter the Fire along with those who enter!“ (Noble Quran).
The Quran is an esoteric book detailing many subjects, and contains prophecy about the coming Judgement and Day of Resurrection. Allah is the God of Israel. This is the KEY to understanding the book. It also has to be understood from a Hebraic Christian perspective since most of its content references Biblical characters in the Old and New Testaments.
An example of the esoteric: In the gardens of Paradise, the righteous, “their light will run forward before them and (with their Records) -- Books of deeds) in their right hands. They will say: “Our Lord! Keep perfect our Light for us [and do not put it off till we cross over (a slippery bridge over the Hell) safely] and grant us forgiveness. Verily, You are Able to do all things.” (Surah 66:8).
The Quran is a commentary on existing scriptures, The Gospel and Torah also containing interesting information from other works like The Testament of Solomon, The Infancy of Jesus Christ and some knowledge of the 3 Enoch.
