The whole book of bible how come no religion such as Muslim?

Only the word Christian is found
The word Christian is used three times in the New Testament: Acts 11:26, Acts 26:28, and 1 Peter 4:16. The original usage in all three New Testament verses reflects a derisive element in the term Christian to refer to followers of Christ who did not acknowledge the emperor of Rome.

Correct bro, the noun "Christian" - used three times - was a nickname coined and used by outsiders in the NT and is also in the context of use by unbelievers. Its modern connotation is of someone who has somehow "arrived" among the saved or at least "crossed the line." It's a static word lacking any sense of further progress.

The favourite title for believers in the early Church - shown in Acts - was "disciple," which is much more dynamic, implying someone who goes on learning from and following their master. It conveys the idea of being "on the way," rather than having "crossed a line." Significantly, the first title for Christian belief and behaviour was "The Way." (again, see Acts)
