Ash-hadu an laa ilaaha ila Allah
Wa ash-hadu anna Muhammadan rasul-ullah
I bear witness that there is no God worthy of worship other than Allah (Allah is the name that belongs to the One and Only God)
And I bear witness that Muhammad is the Messenger of Allah
I am working on this one;
Allah = what Muslims, as well as Arabic-speaking Christians and Jews, call God. I.e. The One Who deserves all worship.
Alhamdulillah, I do not suffer from anxiety attacks, but if anyone does this is said to be helpful.
Allah = the name that only God has
Dhikr = remembrance of Allah
