I have been considering converting to Islam for a couple of weeks, but I haven't actually made the step. However, I have prayed at the mosque several times, and today, I actually performed Salat-al-'Asr at home. Since I said the Shahadah in the iqama and tashahud, does that make me a Muslim? I didn't intend to convert, and I didn't fulfil all the nine requirements of the shahadah.
Am I a Muslim? My niyah was not to convert, but does performing the prayer and saying the shahadah in the tashahud make me a Muslim? Do I have to make up all the prayers I missed since I recited the tashahud?
