For the sake of Allah! That was the most inaccurate website ever! Here I'm going to point out where fact blends into propaganda
1. Allah meaning 666
Below (left) are photos of Greek symbols translated in the Bible as 666, from Free Jesus.net: The gold symbol (bottom and right) is Arabic for "Allah" when turned and mirrored. Additionally, crossed swords are a symbol for Islam. So in 666 we may find symbols for both "Islam" and "Allah".
Now what we see he is a common mistake seen by other religions. We don't believe in symbolism. Also the word Allah can be writin in two ways the 'Sword' is the letter Al. It can be put in the middle or in the back. Also that giant dot above it means "The high and mighty" it's a saying after you say Allah. The also Greek word is not added making it unusable due to no solid proof.
2. The letter qaf and the 666 are never said in any Hadith nor in the Quran. The letter qaf is said when you open a chapter after seeking refuge from the devil and saying in the name of god. Like Al-Baqra,the cow, you say Alif dal meme.
3.The Quran does not have stylistic ways. We don't believe in that. If you want beautiful CALLIGRAPHY look the jewelry. The picture that says "the Quran is 666" is followed up with no proof. Making it void.
4. The "words of a Muslim" are not quoted correctly because you have to add who said them. I have never in my life heard of these ideas that are said to come from a Muslim mouth.
5. Finally the extremely false statement that the Islamic empire is where the seat of the devil is. Let point out this idea is flawed in many ways. Many empires ruled that area. Even the Jews not the throw shade at them. The crusaders ruled the areas. And many others like Byzantium,Rome.and he Pagan Persians. Just because Muslims live there doesn't mean that it's where the devil abides. The majority lives in Indonesia. So by your logic that's where you devil is.
So to pull it all together I hope you see not all resources are right and please notice i am using PROOF and not OPINION. If you can show a logical direct mention of Islam in the Bible with piles of proof and not a guy wearing a tin hat hating in his basement. Thank brother I hope that you have a great day.
