You remember the childhood tales about giants and how you were told that they were really huge and tall people who walked the earth many years ago? Some stories even say they ate small people. Well I can’t verify the latter part of the story but what I can tell you for sure is that giants really existed.
Prophet Muhammed (pbuh) said: “Allah created Adam, making him 60 cubits tall (~27 metres). When He created him, He said to him, “Go and greet that group of angels, and listen to their reply, for it will be your greeting (salutation) and the greeting (salutations of your offspring).” So, Adam said (to the angels), As-Salamu Alaikum (i.e. Peace be upon you). The angels said, “As-salamu Alaika wa Rahmatu-l-lahi” (i.e. Peace and Allah’s Mercy be upon you). Thus the angels added to Adam’s salutation the expression, ‘Wa Rahmatu-l-lahi,’ Any person who will enter Paradise will resemble Adam (in appearance and figure)”.(Translation of Sahih Bukhari, Volume 4, Book 55, Number 543)
From this we see that giants simply refer to the first men. Man has been decreasing in size since then.
The holy Quran also speaks about the people of ‘Ad and Thamud. They were huge and powerful, and could uproot trees with their hands. They were also civilized and skilful. But because of their strength and wealth, they rejected the truth and caused a lot of havoc and mischief on the land. So Allah punished them. Allah wiped them off the surface and it was as though they never existed.
Allah says in the holy Quran in Surah 41:15: “As for ‘Ãd, they turned arrogant on earth, opposed the truth, and said, “Who is more powerful than we?” Did they not realize that GOD, who created them, is more powerful than they? They were unappreciative of our revelations.”
And Also in Surah 89:6-9: “Saw you not how your Lord dealt with the ‘Ad (people). Of the (city) of Iram, with lofty pillars, The like of which were not created in the land? And (with) the Thamud (people), who hewed out rocks in the valley?
The hadith also informs us that the people entering paradise will be as huge as the first man, Adam. Allah’s Apostle said, “The first group of people who will enter Paradise, will be glittering like the full moon and those who will follow them, will glitter like the most brilliant star in the sky. They will not urinate, relieve nature, spit, or have any nasal secretions. Their combs will be of gold, and their sweat will smell like musk. The aloes-wood will be used in their centers. Their wives will be houris. All of them will look-alike and will resemble their father Adam (in statute), sixty cubits tall.” (Translation of Sahih Bukhari, Volume 4, Book 55, Number 544)”
Although scientists continue to dispute concerning the existence of giants, Muslims have all the clarity they need on the matter. Like many matters, science may never find the answer or when they do, it’ll be after a long time. Allah is the Knower of all things.
