Holy Prophet Peace Be Upon Him And His Sunnah

Asalam o Alekum Wa Rehmat Ullah!


Sunnah means the act of any person And sunnah of Holly Prophet Peace Be Upon Him means the act of Holly Prophet Peace Be Upon Him. i would like to clear the difference between Sunnah of Holly Prophet Peace Be Upon Him and biddah (new creation in Dean).
i will discuss 3 main Point in this article 
1) Which Sunnah of Holly Prophet Peace Be Upon Him is Compulsory for Muslim?
2) what is Biddah (new creation in Dean)?
3) Duties of Mulim.
Now I Am going to Describe First point which is "Which Sunnah of Holly Prophet Peace Be Upon Him is Compulsory for Muslim?" Sunnah of Holly Prophet Peace Be Upon Him means the act which Holly Prophet Peace Be Upon Him did in his life there are so many acts of Holly Prophet Peace Be Upon Him which Holly Prophet Peace Be Upon Him did in his life but evry act is not compulsory for Muslims without those Sunnah which was followed by four Khulafa-e-Rashdeen ( Hazrat Abu Bakar Razi Allah o Anho, Hazrat Umar Razi Allah o Anho, Hazrat Usman Razi Allah o Anho and Hazrat Ali Razi Allah o Anho). Every Muslim must have to follow the Sunnah which was done by  Holly Prophet Peace Be Upon Him and Four Khulafa of  Holly Prophet Peace Be Upon Him. 
2nd Point which is "what is Biddah (new creation in Dean)?" is very importent thing to know. Allah says in Quran O 
Holly Prophet Peace Be Upon Him today we have completed You Dean for You and Slectes Dean-e-Islam for you as a favourite Dean. in the light of this Verse we should think that when Allah said we have completed you Dean then we are not able to make any new thing or we cant not change any Rule of Allah and His Holly Prophet Peace Be Upon Him. Once The Holly Prophet Peace Be Upon Him said "Every new Creation In Dean is Biddah And every Biddah Is Misguided and its a way for Hell" in thse days we see so many our Muslim Brothers and Sisters make new things in Dean and think that its a good deed. Which is totaly biddah we should think that we are nothing on the front of Allah and His Holly Prophet Peace Be Upon Him so when they said Dean has been Completed we are not able to Create any thing new in that Dean.............
