Not Qur'an~ rather Islam... Trying to understand the timeline and why these people didn't see the Giants? They were the Giants?
Nib,there are some within Islam folklore that believe Adam was a giant,as well as Moses and Noah. The many legends of giants can be found in just about all cultures and faiths of people.
I most certainly believe there were giants,but just like anything else the "Fish Story" can and will be distorted.
Some snippets....."Be sure and click on the link."
"In Islam, according to Al-Tabari and others, Adam and Eve were giants. Their children were giants. The descendants of their children were giants. Eventually, the giants died out and modern humanity emerged."
"Al-Bukhari picked up Adam’s story at this point, remarking that “Allah created Adam, making him 60 cubits tall [about 90 feet].” But Adam was not done shrinking. As the generic symbol of mankind, his reduction in size continued until he reached the current human height of approximately six feet. Al-Bukhari added, “People have been decreasing in stature since Adam’s creation.”
"While modern sexual reproduction had begun, the human offspring of these early matings were not quite the same as humans today. Obviously, they were giants; two giants such as Adam and Eve necessarily produce giant offspring. Just as important, however, they were hermaphrodites or dual-sexed. This androgynous condition of early humanity was veiled under the theme of twins, “Every boy born to Adam was born together with a girl.”
"Climactically, there was bloodshed and Cain killed Abel. But this was not meant to be taken literally. It was the ultimate metaphor for the deflowering of Abel’s womanhood and, consequently, the shedding of blood. The blood of Abel represented the blood of womanhood."
"The story of Adam and Eve closes with the birth of their son Seth. This is the most important story of them all because Seth was the first modern human being. That is, he was “born without a twin.” This implied that Seth was not a hermaphrodite. He was a fully gendered man. Unlike the children of Cain who were made sterile and eventually swept away by the Flood for their wicked ways, the children of Seth prospered."
"Eventually, the children of Cain died out and only the children of Seth remained, “All the children of Adam today trace their pedigree back to Seth. That is because the offspring of all the other children of Adam except those of Seth have completely disappeared, and not one of them remains, Thus, the pedigrees of all people today go back to Seth.” In simple language, this means that the huge, hermaphrodite giants of the early human races died out and were replaced by the small, fully gendered, human beings of today."
"It is necessary for a man to re-approach the Holy One because Adam, through his choice or sin, dropped out of the higher heavens into material exile. As he fell, his “garments of light” were replaced with “garments of skin.” Eve, who was “attached to his side” as his hermaphroditic counterpart, ceased her clinging, separated from him, and brought about the end of his androgynous condition. As a result, his “beauty deteriorated, his height diminished, and he became one hundred cubits tall.” Once separated, Adam and Eve began to mate with evil demons, or jinn, producing terrible, monstrous offspring, “From Cain descended all those insolent wicked sinners of the world. . . all the haunts of maleficent species, spirits, demons, and sorcerers.” Cain’s descendents, as sorcerers, were huge giants devoid of moral conscience. But Adam had a son, Seth, who was unlike Cain. Seth and his descendents possessed the innate capacity to become the Perfect Man, “All the generations perfected by Seth were entirely righteous and devout.” The children of Seth, who were civilized enough to fashion weapons in their defense against the monstrous offspring who fought with their bare hands, went to war against the evil generations of Cain’s children. The righteous humans went to war against the “Mighty Giants” of the early races. These were the giants spoken of in Genesis 6:4, the children of the sons of God who came to the daughters of men to produce “mighty men, who were of old, men of renown.” Though mighty giants, they had shrunk since Adam’s day; each of them was “fifteen cubits [approximately twenty-two feet] high.” It was these twenty-foot giants who were destroyed in the Flood when the “waters prevailed fifteen cubits upward, and the mountains were covered.” (Genesis 7:20) These giants had to be destroyed. They were thoroughly evil. Not only were they crossbreeding with the demons or jinn of the world, but they were attempting to crossbreed with the righteous line of descendents from Seth. This would have been disastrous for his bloodline. The impure Atlantean blood had to be kept separate from the more pure blood of the up and coming human races. No story captured this better than that of Moses killing the giant Og; the story appeared in the Babylonian Talmud, compiled before 500 AD, and later re-appeared in Al-Tabari’s history. Moses, whose height was “ten cubits,” took an “axe ten cubits long, leapt ten cubits into the air,” and struck Og, who was far taller than ten cubits, on “his ankle and killed him.”
"There is but one allusion to giants in the Qur'an, namely to the tribe 'Ad who are spoken of as men "with fifty statures" (Surah lxxxix 6), and the commentator Shah 'Abdu 'l-Aziz of Delhi, says they were men of not less the twelve yards in stature. According to a tradition in the Kitabu 'sh-Shafah by the Qazi 'Ayaz(p 65), Adam was sixty yards in height. In the Ghiyasu 'l-Lughah, a giant named Uj is mentioned who was born in the days of Adam and lived until the time of Moses, a period of 3500 years, and that he was so high, that the flood in the days of Noah only reached to his waist. There are traditions and stories of giants whose graves exist unto the present day, throughout the whole of Persia. Opposite the Church Mission House at Peshawur is a grave nine yards long, which is held in great reverence by both Muhammadans and Hindus. De le Belle, in his Travels in Persia, vol ii p 89, mentions several which exist in Persia. Giant graves in Hindustan are numerous."
