The Statement of At-Tawhid: La ILaha Illa-Allah (Its Virtues, Significance, Conditions, & Nullifiers) By Shaykh ʿAbdur-Razzāq Ibn ʿAbdul-Muhsin al- ʿAbbād al-Badr
The most virtuous of words - the word of Tawhīd- Lā Ilaha Illā-Allāh- will not be accepted by mere utterance on the tongue. Rather, an implementation of its fundamental principles is necessary. For example, disproving polytheism and affirming the oneness of Allāh with a firm belief and adherence to all that it entails. This is the only way can anyone be considered a Muslim or be in the fold of the people of Tawhīd (Lā Ilaha Illā-Allāh). This great word signifies the falsehood of any deity besides Allāh. To affirm any deity other than Allāh is the most atrocious aggression and most evil deviation.
