Re: tasbeeh
i think, my own feeling, is that it was originally 33 times each the tasbeeh, the tahmeed and the takbeer, and then "la ilaha illallahu wahdahu la shareeka lahu........." to make it 100, but since ppl cud not remember the long tasbeeh at the end to complete the 100 they replaced it with a simple takbeer....
so that ppl wont just leave it cuz they cud not memorize the long zikr....
One naration also tells us that it is 33 times each Subhan Allah, Alhamdo Lillah, Allah-o-Akbar and then at the end to read "Subhan Allahey walhamdo LillahaY walaa ilaahaa illal-laaho wallaho Akbar Wala haula wala Quwata Illa billahil ali-yil adheem"
