Orthodox Jews & Christians Prays Similiar To Muslim Namaz .
وَأَقِيمُوا الصَّلَاةَ وَآتُوا الزَّكَاةَ

Oh Muhammed “ establish Salah and give Zakah"

Following verses from the Bible. "And he (Jesus) went a little further, and fell on his face, and prayed..." (Matthew 26:39)
.
"And Joshua fell on his face to the earth, and did worship..." (Joshua 5:14)
.
"And Moses and Aaron went from the presence of the assembly unto the door of the tabernacle of the congregation, and they fell upon their faces…" (Numbers 20:6)
.
"And Abraham fell on his face..." (Genesis 17:3)
.
"…and they fell on their faces before the throne and worshiped God." (Revelation 7:11)
.
"…then they bowed their heads and worshiped the Lord with their faces to the ground." (Nehemiah 8:6)
.
"…Then David and the elders of Israel, who were clothed in sackcloth, fell upon their faces." (1 Chronicles 21:16)

In many others places in the Bible where we find the method of prayer mentioned, it calls to mind the way Muslims pray. In the Bible book entitled Daniel we are able to read a description of Daniel praying to God in a time of great crisis.
.
"Now when Daniel knew that the writing was signed, he went into his house; and his windows being open in his chamber toward Jerusalem, he kneeled upon his knees three times a day, and prayed, and gave thanks before his God, as he did a foretime." (Daniel 6:10)

It is interesting to note that Prophet Daniel prayed towards Jerusalem. In the early days of Prophet Mohammad’s mission the faithful also prayed towards Jerusalem. However the Muslim direction of prayer changed. About sixteen months after Prophet Muhammad and his followers migrated from Mecca to the city of Medina the direction was changed to facing the sacred House of God in Mecca.

Descriptions of the positions Muslims adopt in the five ritual prayers per day can be found throughout the Bible. Many are mentioned in the book of Psalms.
.
"Stand in awe, and sin not."(Psalms 4:4)
.
"O come, let us worship and bow down: let us kneel before the Lord our maker." (Psalms 95:6)
.
"…all that go down to the dust shall bow before him…" (Psalms 22:29)

And in the book of Kings we find Prophet Elijah casting himself upon the earth in the position of kneeling before touching the forehead to the ground.

"…and he cast himself down upon the earth, and put his face between his knees." (1 Kings 18:42)

This is a position very familiar to Muslims. So too is the position Jesus adopts during prayer in a moment of fear and uncertainty.

"And he (Jesus) was withdrawn from them about a stone’s cast, and kneeled down, and prayed." (Luke 22:41)

Allah Say's To Prophet Muhammad Pbuh

[Quran 16:123] "Then we inspired you (O Muhammad) to follow the religion of Abraham, monotheism; never was he an idol-worshiper."

[Quran 19:58] "These are some of the prophets whom God blessed. They were chosen from among the descendants of Adam, and the descendants of those whom we carried with Noah, and the descendants of Abraham and Israel, and from among those whom we guided and selected. When the revelations of the Most Gracious are recited to them, they fall prostrate, weeping.

"[Quran 19:59] "After them, He substituted generations who lost the Contact Prayers (Salat), and pursued their lusts. They will suffer the consequences.
