Jesus is described in the Gospels as prostrating during prayer. In Matthew 26:39,the author describes an incident which took place when Jesus went with his disciples to Gethsemane: "And going a little farther he fell on his face and prayed, ‘My Father, if it be possible, let this cup pass from me; nevertheless, not as I will, but as thou wilt." Christians today kneel down, clasping their hands, in a posture which cannot be ascribed to Jesus. The method of prostration in prayer followed by Jesus was not of his own making. It was the mode of prayer of the prophets before him. In the Old Testament, Genesis 17:3,Prophet Abraham is recorded to have fallen on his face in prayer; in Numbers 16:22 & 20:6, both Moses and Aaron are recorded to have fallen on their faces in worship; in Joshua 5:14 & 7:6, Joshua fell on his face to the earth and worshipped; in I Kings 18:42, Elijah bowed down on the ground and put his face between his knees. This was the way of the prophets through whom God chose to convey His word to the world; and it is only by this way that those who claim to follow Jesus will gain the salvation which he preached in his Gospel.

"Jesus (peace be upon him) prostrated in prayer, a clear sign of his submission to Allah, just as Muslims do. The Bible says, ‘He fell on his face and prayed' (Matthew 26:39) in the Garden of Gethsemane, humbling himself before his Lord. The Qur'an describes him as a devoted servant: ‘When Allah said, "O Jesus, indeed I will take you and raise you to Myself"' (Surah Aal-E-Imran, 3:55). Prostration is the ultimate act of worship, and Jesus did it to seek Allah's help, not as God praying to Himself.
In Islam, we prostrate in salah, following the way of the prophets: ‘O Mary, be devoutly obedient to your Lord and prostrate' (Surah Aal-E-Imran, 3:43). Jesus' prostration mirrors this—prophets like Abraham and Moses (peace be upon them) did the same. It shows he was a human messenger, not divine, worshipping Allah alone. His example strengthens Islam's call: bow to the Creator as Jesus did, in total surrender and reverence."
Surah Al-A'raf, 7:206
Jesus also looked straight up to the sky to pray directly to the Father several times. He also seems to pray while looking straight forward. There doesn't seem to be any consistent method in which Jesus prayed as he knew God was everywhere and he is God.
As for the other prophets, many of them also looked up to the sky to pray to God. The practice of only bowing down and prostrating to God is not a Jewish or Christian practice. It is not based in the bible. Some even danced while praying and praising God.
