THE RITUAL PRAYER (NAMAAZ) AND MORE
I am a Zoroastrian. Dr. Shabbir's research is quite right. Your NAMAAZ was stolen from Zoroastrianism by your Parsi Imams from Persia.
It would be appropriate if we can discuss the startling similarities between some practices of Islam and Zoroastrianism. These parallels go beyond coincident. I will endeavor to enumerate a few here:
01. Requirements of prayers: Islam enjoins its followers to pray 5 times a day and is called by the Muezzin to his prayers.These prayers are at i) Dawn ii) Noon iii) Afternoon iv) Sunset v) Night.
Zoroastrianism also enjoins prayers 5 times a day called "Geh". The devotee is summoned by the ringing of a bell in the AtashBehram / Agiary. These prayers are also at the same time as in Islam and their respective names are:
Time: Islamic/ Zorastrianism
Dawn: Fajar/ Havaan
Noon: Zohar/ Rapithwan
Afternoon: Asr/ Uziren
Evening: Mazreem or Maghrib/ Aiwisuthrem
Night time: Isha or Ishan/ Ushaen.
02. Pre-requisites of Prayer: On entering the mosque and prior to commencing prayers a Muslim has to cover his head and wash his face and limbs. Similarly, a Zoroastrian on entering the Agiary will cover his head, wash his face and limbs and perform the Padyaab Kusti before commencing his prayers.
03. The Prayers: Prayers in Islam are in Arabic only, though translations/transliterations are available. The liturgy has to be conducted in Arabic only. In Zoroastrianism too, prayers have to be recited in Avesta or in Pazend only. In fact in Aveatan prayers Pazend portions have to be recited in an undertone so as not to break the seamless flow of Avestan Manthravani.
04. Sanctum Sanctorum and its veneration: The holiest spot in a Mosque is the wall facing Mecca and is called the Qiblah. In the Atashbehram/Agiary the room where the Atash Padshah is enthroned is also called the Keblaah. A Muslim will perform the Sajdah in front of the Qiblah and so also will the Zoroastrian perform the Sezdah before his Keblaah. Both involve kneeling down and touching the forehead to the ground.
05. A Holy Month: In Islam Ramzan is the holy month in which all Muslims are required to fast in the day and only break their fast after sunset. In Zoroastrianism the month of Bahman has similiar connotations wherein all are requested to particularly abstain from flesh. Perhaps in the age of the Sassanian dynasty the month of Bahman was observed as Ramzan is now.
06. Ascent into Heaven: The hagiography of Islam assures us that Prophet Mohammad ascended to heaven from Jerusalem on the mythical beast Burrrak. He crossed the 7 spheres, exchanged greetings with the patriarchs and beheld the glory of God.
The Dinkard tells us that at the entreaties of Asho Zarthustra Bahman Ameshaspand transcendentally elevated his consciousness to the realm of heaven wherein Asho Zarthustra looked at the reflugent majesty of God. A similiar journey was attributed to the virtuous Ardaviraf who visited hell, purgatory and heaven during his spiritual journey.
The above similarities are obvious. A more careful research would reveal more parallels. However even these points are too close to be dismissed as mere coincidences. This means Zoroastrianism has had an enormous impact on Islam which is not acknowledged. Everyone agrees Islam owes a lot to Judaism and Christianity but I feel that the scholars of Islam borrowed very heavily from Iran and this can be perhaps attributed to that shadowy figure of Dastur Dinyar (Salman Farsi). This debt is so impressive that it had to be consistently downgraded and later denied. After all if Islam is supposedly directly inspired by God it cannot be seen to be acknowledging any debt to an older faith, specially the faith of a nation which Islam has defeated. This may perhaps explain the devotion of your Persian Imams to my Faith.
07. Chinvat Bridge (The SIRAAT BRIDGE): According to ancient Persian myth, when a person dies, the soul remains by the body for three days. On the fourth, it travels to Chinvat Bridge (the Bridge of the Separator, also call Al-Sirat), accompanied by gods of protection. The bridge is "finer than a hair and sharper than a sword" and spans a deep chasm teeming with monsters. On the other side of the bridge is the gateway to paradise.
08. Hell: Demons guard the foot of the bridge and argue with the gods over the soul's fate. The actions of the dead person, both good and bad, are weighed, and the soul is either allowed to cross or denied access to the bridge. Spirits whose evil outweighs their good fall into the demon-infested pit to face eternal torment. In this abyss of the damned, each soul is tortured by a GHOUL that represents its sins in life. Once fallen into the gulf, no soul can escape the horrors of hell through its own power.
Zoroaster, a sixth century BC religious leader, had warned his followers of this obstacle to heaven but he promised to lead his flock safely across. The ancient manuscript Gathas (Songs of Zoroaster) explains that the Bridge of the Separator "becomes narrow for the wicked," whereas the holy can easily pass unharmed. (In Gathas, the fair god Rashnu is named as the judge who helps determine who is worthy of salvation and who must be damned.) All infidels (non-believers) fall into hell, which the prophet says has been created especially for the "followers of the lie."
The legends are sketchy but assert that Chinvat Bridge is located somewhere in the far north. It is a place of filth where the damned endure physical tortures and spiritual agony. Souls who are unsuccessful in crossing the Chinvat Bridge suffer these torments until AHRAMAN, the evil god of ZOROASTRIANISM, is destroyed by the good god Orzmahd during the LAST JUDGMENT. As this time, lost spirits are restored to the truth since "the lie" has been eradicated, or they face final ANNIHILATION.
Notice the similarity? So you guys are actually pagan stone and sun worshippers, correct? But your Koran is pure and free from plagiarism.
THE FIVE RITUAL ZOROASTRIAN PRAYERS
The five prayers were developed AFTER the Prophet Zoroaster.
See below some quotes on the ritual prayer ceremony:
From the book J.J. Modi: The Religious Ceremonies and Customs of the Parsees. (Bombay, 1922.) Part 3.
1. There are three grades of the Sacred Fire-(A) The Sacred Fire of the Atash Behram, (B) that of the Atash, Adaran and (C) that of the Atash Dadgah. These three have their different rituals of consecration and also different rituals for the daily prayers at the five times (gahs) of the day, when they are fed with fresh fuel. We will, at first, speak of the process of consecrating these three grades of the sacred fire. For example, he falls on his knees in his prayers; he lowers his head and bows; he raises his hands towards Heaven. All these ways or rites, which symbolize service or obedience or homage to God, are done occasionally.
The candidate is to say his prayers five times during the day. He is expected to pass his time in a religious or pious mood. The candidate  has, during these six days, to pass his time in prayers during the five Gahs and to observe all the observances of saying the grace at meals, etc. He is not to come in contact with any non-Zoroastrian.
The five periods for the performance of the ceremony:
The Bui ceremony is performed five times every day. It is performed at the commencement of each of the five Gahs or periods of the day which correspond to a certain extent, with the canonical hours of the Christians.
18 These periods are the following:
(1) Hawan. It begins from early morning when the stars begin to cease to appear, and lasts up to 12 O'Clock when the sun comes overhead. Literally, it means the time when the ceremony of pounding the Haoma is performed.
(2) Rapithwin. It runs from 12 o'clock noon to 3 p. m. Literally, it means the pith (pithwa) or the middle part of the day (ayarê).
(3) Uzerin. It runs from 3 p.m. to the time when the stars begin to appear. Literally, it means the time of the advancement of the sun.
(4) Aiwisruthrem. It runs from nightfall to midnight.
(5) Ushahin. It runs from midnight to dawn when the stars begin to cease to appear.
The priest performs the Kusti-padyab (i.e., performs ablutions and unties and puts on the Kusti again with the recital of a prayer).
The Bui ceremony in an Atash Behram: A priest who has performed the Khub ceremony, performs the Kusti-padyab at the commencement of each new Gah, i.e., the period of the day, as described above, and then recites his Farziyat, i.e., the necessary prayers, which are the Srosh-baj, the Gah according to the time of the day, and the Khwarshed and Mihr Niyayeshes during the day periods, i.e., the above named first three gahs.
During the night-periods which form the last two gahs, the Khwarshed and Mihr Niyayeshes are replaced by Srosh Yasht (Yasna 57) and Srosh Hadokht. He then goes into the sacred chamber, puts on white gloves, places some frankincense over the Sacred Fire, and then the Mâchi, i.e., the six pieces of sandalwood as said above. If  sandalwood is not obtainable, six pieces of any other kind of clean good wood will do. The six pieces are placed over the fire from three different positions, thus:
