Sunnah

Obeying Nabi (sallallahu alaihi wasallam)

Q: Is it mentioned in the Quran that obeying the Messenger is obeying Allah? When I asked someone that who should we obey more, Allah or the Holy Prophet (Sallallahu Alaihi Wasallam)? They said obeying The Holy Prophet (Sallallahu Alaihi Wasallam) is the same as obeying Allah. Does it mean that we should equally obey them, wound we fall into shirk as we are obeying someone equally to Allah?

Carrying out a sunnah action without making the intention

Q: An act that's sunnah. When one started it, it was done with the niyyah of sunnah. After years you become accustomed to it, it becomes a habit like dusting the bed or reading certain duaas or eating with the right hand, etc. Will you still get the thawaab of practicing a sunnnah or will the niyyah be have to made every time you do an action? Some aalima said that one won't get rewarded without the intention.
