Re: Rolling Tasbeeh: Islamic or not
Counting has developed from a literal undertaking of various hadith ... such that so much recital gives so much reward or protection or cure, etc.
Showing off is debatable as we pray infront of people and away from them we give charity infront of people and away from them this is to encourage them to do the same.
Endlessly doing something good as a measure of piety goes against the edicts we learn in Islam which are:
We should do little but as perfectly as we can ... and that one who prays 10 prayers thinking them to be duty has changed the requirement of the 5 obligatory prayers.
