Re: Kissing one's eyes when hearing the name of the Prophet (SAW)
^-- for one, it is definitely not fashionable to criticize things as bid'ah :) The purpose is simply this: When Allah (swt) tells us that Islam is complete, and the Prophet (saws) warns us against introducing things in religion, people ought to get the message. For me standing upside down during salah may not be biddah, but it is simply because it introduces into the deen of islam.
The principal regarding religious activities is that everything is considered prohibited UNLESS a proof exists from the Quran or Sunnah. Announcing the adhaan for salaah can not be considered biddah simply because the religious activity remains the same- announcing the time for salaah, i have not put in something new like new words in the adhaan etc, which WOULD be a biddah.
I dont understand your argument about collecting the quran.. i'm not sure which activity Abu bakr (ra) introduced into islam? Do we not still recite the quran, understand it, try to implement it, etc? Or are we doing something new and innovated regarding the Quran?
