Reminds me of Khalid Yassin when he converted 20 Aussie & said to them “now we don’t have a pool for you in the back side to jump into”, anyway…
Once you’re fully convinced with the teachings of Islam, you are actually a muslim, i.e once you realize that Allah is one & Mohammad was his servant & final messenger to the world, you’ve technically become a “muslim” <— which literally means “submitting”, & then you have to confirm this submission officially by declaring/saying : " i bear witness that there’s no god but Allah, & i bear witness that Mohammad is the messenger of Allah "
No ceremony needed, unless you feel like celebrating…
In Morocco, usually people comes to a mosque & declare their “shahada” infront of people so they can be witnesses for them on the judgement day, & the people celebrate the new convert by saying “Allah Akbar” 3 times (this is Islamic tradition not Moroccan invention)
After that, the Imam asks the new convert infront of people : “what new name will you choose?” & this is not an obligation, i mean it’s common & normal to answer by “i haven’t decided yet”
After converting, the following steps are recommanded:
reading the detailed biography of Mohammad : “you don’t put pure water into a dirty pipe & expect it to come out pure from the other side, this pure religion must have come through that pure man” - Yusha Evans (a convert)
The Shahada was the first pillar of Islam, the second is prayer & it needs ablution, it’s the principal mean of the special personal relationship with Allah, so it has to be learned.
