What I learned 31/7/2012
Taking Shahada with the tongue IS sufficient to become a Muslim.
It is NOT sufficient, however, to imprint Islam in our lives which is what we as good Muslims should be aiming for.
Entering Islam "Perfectly and Wholly" (as mentioned in Surah Baqara 2:208) requires much more than just Shahada.
In fact, not a single moment should pass under the influence of disbelief or hypocracy.
