Re: Sunnah Way…
None of the above acts anyone follow as part of Fard or Sunnah. So, such acts are individuals’ personal decision to follow. If Allah would accept it as good deeds then fair enough, but not then there is no sin.
Only acts that a person follows as fard or sunnah could carry sin if they are not fard or sunnah, as then they would be bohtan. If followed by considering something fard then it would be bohtan on Allah who did not made such fard. If followed by considering them as Sunnah then it would be bohtan on prophet (SAW) whose Sunnah it was not.
Bidah is doing something considering it fard what was not fard, as then it becomes bohtan on Allah. All bohtan carries sin, especially bohtan on Allah and Prophet (SAW).
[Only fard is prescribed Ibadah of Allah and anything that one adds with fard and make it fard, is bidah]
