«من شهد أن لا إله إلا الله وأن محمدا رسول الله حرم الله عليه النار»
The Prophet (peace and blessings be upon him) said:
"Whoever bears witness that "La ilaha illallah wa anna Muhammadan rasulullah" (there is no god worthy of worship except Allah, and Muhammad (peace and blessings be upon him) is the Messenger of Allah), Allah Almighty will forbid the Fire for him."
