So sorry I did not answer sooner, not feeling well. Al-humdililah you have taken this step sister. It is a day everyone on curezone should be praising Allah. Al-hundililah Allah has called you home and chose to save you from the hellfire.
A shahada can be said anywhere and it can be done in private. If you are not close to a masjid we are sorry to hear that but there are many ways to worship Allah alone and in private. Take a shower first, do wudu and then recite the shahada.
If you don't know the words then let me know. Some do not understand but it is simple .
La illah illah lah Mohammad rasul ulah.
I testity that there is no other God but Allah and that Mohammad is his messenger.
Walah you are a Muslim.
The shahahda also states that you believe in
His books (Quran, bible and torah)
You will do pilgrimage is financially able but a woman without a husband who is Muslim cannot do this. Her intention alone is enough.
Fasting of Ramadan
If you are being tortured and it would cause you harm to tell others you are a Muslim then you may keep your religion a secret.
I will make a prayer for you and pray for this shahada to come easy for you. Again forgive me as I was not aware of any message here. I must contact the Webmaster and see why.
