My brothers and sisters in Islam, As-salamu ‘alaikum!
To testify that there is One Creator who sustains, nourishes, and controls is not enough for the Muslim. The Muslim is one who believes and testifies that indeed Allah is the Creator, the Nourisher, the Sustainer, and also affirms that ONLY He is worthy of worship.
