The Prophet (peace and blessings be upon him) said: “Islām is built upon five: The declaration that there is none worthy of worship except Allāh and that Muhammad is the Messenger of Allāh…” (Bukhārī and Muslim) The first pillar is the duty to declare the two great beliefs of Islām: these are to believe in the Oneness of Almighty God in worshipping Him alone and in the Prophethood of Muhammad as the final Prophet and best example to be followed. The Shahādah is to utter: Ash-hadu an laa ilaaha illallaah, wa ash-hadu anna Muhammadan ‘abduhu wa rasooluhu (I bear witness that none has the right to be worshipped except Allāh alone – and I bear witness that Muhammad is His slave and messenger). These words, laa ilaaha illallaah specifically, are repeated throughout the life of the Muslim. Laa ilaaha illallaah is the heaviest of good deeds on the scales on the Day of Judgement (Hadeeth). It is best of what the Prophets and their followers uttered in ‘Arafah during Hajj (Hadeeth). It is the best utterance of remembrance (dhikr). The complete Shahādah is declared aloud during the Adhān (the call to Prayer). It is declared during every prayer in the “tashahhud” whilst seated by obligation. It is the best that can be said before one’s passing away, “Whoever’s last words are laa ilaaha illallaah (None has the right to be worshipped except Allāh) will enter Paradise.” (Hadeeth) The Shahādah is the key to Paradise, without its utterance a person cannot be a Muslim. The Shahādah is also written on the green Saudi flag.
