Ash hadu an laa ilaaha illallaah, wa ash hadu anna Muhammadan rasool-ullaah
(I bear witness that there is no god worthy of worship except Allah and that Muhammad is the Messenger of Allah)
Why the Statement “Laa ilaaha illallaah”?
Because it is the first duty of a Muslim. Therefore, whoever intends to accept Islam must make such a declaration of faith and believe in it.
Because whoever says it, sincerely believing in it and seeking thereby Allah’s pleasure, will be saved from Hellfire, as the prophet ﷺ said, “Allah has forbidden for the Hellfire anyone who says, ‘There is no one worthy of worship except Allah,’ seeking thereby Allah’s pleasure.” (Saheeh Al-Bukhaaree: 415)
Because whoever dies while believing in it will be admitted into Paradise, as the prophet ﷺ said, “Whoever dies knowing full well that there is no god but Allah will enter Paradise.” (Musnad Ahmad:464)
Because knowledge of its meaning and dictates, is unquestionably the greatest and most important duty of a Muslim.
The Meaning of Laa ilaaha illallaah
This means no one is worthy of worship except Allah. In fact, this statement negates the existence of any other deity besides Allah ﷻ and confirms that Allah is the only True God worthy of being worshipped.
