Al-Tawhid is an Arabic term that refers to the oneness of Allah or the unity of God. In Islam, this concept is of great significance as it is considered one of the fundamental beliefs. There are various synonyms for the word al-tawhid, including "tawheed," "ahad," and "wahdaniyya." Tawheed refers to the belief in the oneness of Allah, while Ahad denotes the singular, indivisible nature of Allah. Wahdaniyya, on the other hand, emphasizes the concept of unity and highlights how Muslims must strive to follow God's teachings and unite in their worship of Him. These synonyms all contribute to conveying the profound importance of al-tawhid in the Islamic faith.
