Yes,  of course, Jesus was Prophet but not son of God rather son of Mary. Among Prophets he was very very special. God created  ADAM without father and mother. God created EVE without mother. God created Jesus without Father. God created rest of mankind with father and mother. So Jesus became very very special by birth after ADAM and EVE. 

Precisely saying the offspring of the grandson of ABRAHAM are called jews. ABRAHAM had two sons, ISMA"EEL and ISAAC. Jacob was son of ISAAC. The chidrens of Jacob are called children of Israel.. The Jacob had 12 sons, so 12 tribes of jews. The JOSEF, Benjaman, SOLOMAN, David, Moses and the Christ, belongs to childrens of Israel. Majority of Israelese did not accept teaching of Christ. By definition, a jew is one whose mother is jew. The most current definition is, the jew is one whose father or mother is jew. Everybody cannot be a jew. If anything else is special...., may be. This is what we are told as being Muslims. Bible also supports it.

Fajr prayer consists of 2 rakats. A leader(commonly called Imam) leads the prayer after AZAN. All people offering prayers direct theirselves to Holy Ka'aba (situated at Makka, in Saudi Arabia, which was built by ABRAHAM. A person recite AQAMA (like AZAN) and then Imam starts by saying, ALLAH -o-AKBAR (The great Lord is the Greatest). then movement other than prayer is strictly forbidden till end of prayer. Imam recites First Chapter of Holy Quran and then adds up a portion of Quran from anywhere in the Quran. Then by saying ALLAH-o-AKBAR Imam proceeds to bowing stage. Their every body speaks TASBEEH (The Greatest Lord is free of any weakness, any defect, any negative traits, the Exalted). Then moves up to standing position. From standing to prostrating (called SAJDA). Raises from to sitting position and then again for SAJDA. One rakat completed. The last rakat of every prayers also include worshiping in the sitting state, where every Muslim pray to The Great Lord what he wants.
