Hello Sami,
First, it is important for you to understand that Muhammad's anti-religion is as opposite to the Gospel, as the negative is to a photograph. Muhammad fills his followers with complete resolve as to what to DISbelieve, DENY and REJECT:
http://www.falseprophetmuhammad.comhttp://www.falseprophetmuhammad.com/islam_is_antichrist.htmNow consider the mathematical odds, of just 5 Messianic prophecies having come true:
http://www.islamandthetruth.com/bible_prophecy.htmLike the Old Testament prophecy of Jesus' crucifixion in Psalms 22 for example:
http://www.islamandthetruth.com/psalms_22.htmSecondly, in the example of your first link:
http://free-minds.org/pilgrimage-lost-legacy-abrahamIt is a geographical impossibility.
First of all the archaeological evidence confirms that Abraham was never within 1,000 kilometers of where Mecca was eventually built in the 4th century AD. The towns that the scriptures describe are confirmed by the archaeological evidence. Indeed his travels were in the opposite direction - within the "fertile crescent" - obviously not in the harsh, barren, Arabian desert.
http://www.historyofmecca.com/Your article suggests an absence of evidence of the temple in Jerusalem, yet there the temple mount still stands today. There are over a million artifacts just on display, in THE Holy Land of the prophets and patriarchs. We have a whole forum section dedicated to the evidence.
http://www.islamchristianforum.com/index.php?board=68.0Yet even as there is abundant archaeological evidence of many ancient Arabian towns, there is not A SHRED of archaeological evidence that suggests that Mecca ever existed prior to the 4th century AD, when pagans migrated there from Yemen and built their Kaaba in the late 5th century for Arabian moon, sun, star and jinn-devil worship.
http://www.falseprophetmuhammad.com/origin_of_ramadan.htmSecondly Islam's dissimulators try to pretend that Psalms 84 suggests that God's people wandered 1200 kilometers across harsh, barren, untraveled, uninhabited, waterless desert, from Jerusalem to Mecca - a thousand years before a caravan route was established along the Red Sea and most of a thousand years before the advent of camel transport - allegedly on pilgrimage to the Quraish pagan's Kaaba that wasn't built until late in the 5th century AD (1500 years after Abraham roamed the earth).
http://www.falseprophetmuhammad.com/evidence_for_islam.htmMost of those taqiyyah peddling dissimulators happen to leave out the most important part of the verse from Psalms 84 - THE LOCATION of the temple that the pilgrimage is to:
Psalms 84:7 They go from strength to strength, [every one of them] IN ZION appeareth before God.
IN ZION (name of the eastern most hill, but used synonymously with Jerusalem), which is mentioned 152 times in the Bible. I corrected those liars over and over in Wikipedia, by adding the most important part of the verse, but they would just come back over and over and erase that most important part, from the very verse they were trying to pretend supported their lies.
http://www.petewaldo.com/baca_mecca.htmI'm sorry my friend, but one can either follow ALL of the prophets and witnesses, as revealed in the 1600 year record of YHWH to mankind, whose people have followed Him through two covenants for 3500 years....
.....or follow MUHAMMAD ALONE who proclaimed the exact opposite of the Gospel through his STAND-ALONE 23 year 7th century record, whose people follow him through adopted, adapted and thinly veneered pagan Arabian moon, sun, star and jinn-devil worship rituals. Indeed Muhammad's followers and the pagans performed jinn-devil worship rituals shoulder to shoulder, up until the year before Muhammad's last Hajj:
http://www.petewaldo.com/hajj_umrah.htm#tawafGod gave you the free will to choose to follow the perfect and sinless Messiah, the Prince of Peace, the Lamb of God, or to choose to follow an imperialistic conquering, innocent slaughtering, female prisoner abusing, thief.
http://www.falseprophetmuhammad.com/jesus_or_muhammad.htmGod gives us each the free will to choose. I pray He will guide you in the truth and help you overcome the false prophet Muhammad's lies, deception and recycled jinn-devil worship.
