Shahada is the most fundamental expression of Islamic belief. Shahada is a declaration of faith and trust that professes that there is only one Allah and Muhammad (PBUH) is his messenger. It is a statement “There is no true god but Allah, means that none has the right to be worshipped but Allah alone, and Allah has neither partner nor son and Muhammad (PBUH) is messenger of Allah. This testimony of faith is called the Shahada, a simple formula which should be said with conviction in order to convert to Islam. This testimony of faith is the most important pillar of Islam.
The Quran shows, in no uncertain terms, that the message and the top priority of all the Prophets (peace be upon them) was one and the same: ‘The message of Tawheed’.
“Allah is the Creator of all things, and He is the One, the Supreme”. (Qur’an: 13:16)
“And those whom they call on besides Allah have not created anything while they are themselves created”. (Qur’an: 16:20)
